So compact, you can carry it in your hip pouch. The GRENOUILLE Model 8-50, for example, measures 33 cm x 4.4 cm x 11.5 cm and weighs just 1.2 kg. GRENOUILLE's highly portable size is important because you never know when you might have to measure an ultrashort laser pulse! For full specifications, see GRENOUILLE Specs.

A simplified FROG device, GRENOUILLE combines full-information pulse measurement with experimental simplicity. GRENOUILLE operates alignment-free, requires only a few simple optical elements, and features an operating range that nicely includes that of most ultrafast Ti:Sapphire lasers and amplifiers.

Compact Storage is a separate area with arbitrarily assigned call numbers designed to store the largest amount of books in the smallest possible space. It is used primarily to store infrequently used material or to protect vulnerable material from unnecessary handling. Both the Holland and Terrell Libraries and the Owen Science and Engineering Library have Compact Storage areas. Contact the appropriate Circulation desk for help in accessing materials from these collections.

Newport Corporation, the worldwide distributor for GRENOUILLE devices, markets and sells them under the UPM (Ultrashort Pulse Measurement) label. UPM and GRENOUILLE model numbers, specifications, and capabilities are identical; only the product name differs.

FROG is rigorous, general, and relatively simple to implement, and it has become a very successful technique, with many accomplishments. The shortest pulse ever generated at the time of this writing (4.0 fs) was measured using FROG. Indeed, autocorrelation measurements (interferometric or otherwise) are no longer acceptable to claim a world’s record short pulse.

Yes, this is the case in all SHG-based pulse-measurement devices. Unlike autocorrelation, which has unaccountably many ambiguities, the direction-of-time ambiguity is essentially the only one in GRENOUILLE. If you’d like to remove it, just place an etalon in the beam before the GRENOUILLE [this is our POLKADOT (Procedure for Objectively Learning the Kalibration And Direction Of Time) option, which will be available soon. You can check out our paper on the subject: E. Zeek, A. P.

Several of the specs are self-explanatory, such as the sensitivity. But interpreting the temporal resolution, spectral resolution, temporal range, and spectral range require some thought. When you make a complete pulse measurement, as you do with GRENOUILLE, you must consider the resolution and range in both the time and frequency domains. The GRENOUILLE temporal range should be a factor of two or more greater than your pulse-length FWHM.

No! Just place the spectrometer behind the autocorrelator, and measure the spectrally resolved autocorrelation, and you have a FROG. You can then just buy one of FROG analysis software packages by Mesa Photonics or Femtosoft Technologies. We just saved you a bunch of money (not to mention the benefit to your research from such improved measurements)! No! FROG and GRENOUILLE are much more sensitive than other intensity-and-phase methods.

GRENOUILLE stands for “GRating Eliminated No-nonsense Observation of Ultrafast Incident Laser Light E-fields.” It’s the French word for “frog.” We’ve chosen it to honor all the great French and French-speaking scientists who have contributed to the field of ultrashort laser pulse measurement, including Jean-Claude Froehly, J. A. Giordmaine, and Jean-Claude Diels.

No, there's no advantage to SPIDER over GRENOUILLE. In the early days (~ 5 years ago), the FROG algorithm was slow (taking up to a minute to converge), and SPIDER's inversion algorithm was faster. But performance improvements in the FROG pulse analysis tools have eliminated SPIDER's only (short-lived) advantage.

Some companies are making safer products today and striving to make even safer products in the future.  More than 600 companies have signed the Compact for Safe Cosmetics, a pledge to remove hazardous chemicals and replace them with safe alternatives within three years.  Click here for the most recent list of Compact signers. Arbonne, Avon, Mary Kay and Melaleuca are aware of the Compact for Safe Cosmetics but have refused to sign it.

Compacting backfill material in 8" to 12" (200mm-300mm) lifts allows you to effectively compact the entire area behind the wall without putting unnecessary pressure on the units. Thick lifts of soil require more compaction effort and create a greater force at the back of the wall which may cause potential alignment and rotation problems. Consult with a geotechnical engineer for further compaction criteria based on specific site soil.

This is a policy that concerns all students who are transferring from a Mass. Community College to a four-year state college or university with an Associate of Arts or Associate of Science transfer degree.

This is a law with which we must comply! Since a child cannot legally cross state lines with any person other than a parent or guardian, we obtain permission from the sending state for the child to leave, and from the receiving state (the adoptive parents’ state of residence) for the child to enter. The Interstate Compact laws are administered differently in each state.

The Compact is governed by the IIPRC, which includes one Member from each Compacting State. The Management Committee of 14 Members directs the activities of the IIPRC.

The Compact will be financed by IIPRC filing fees paid by insurers. The Compact authorizes the IIPRC to accept any and all appropriate donations and grants of money. In March 2006, the NAIC provided a contribution to the IIPRC in the amount of $500,000 to help cover its start-up activities. There will be no fiscal impact on states joining the compact as the IIPRC will collect and remit state filing fees.

Compact Flash is a small form factor that combines non-volatile storage, high-capacity options and industry-standard compatibility, which is absolutely essential for digital cameras and handheld computing devices. Because they are designed to the guidelines set by the CFA (CompactFlash Association), a base-level assurance of compatibility has been set between all-certified Compact Flash cards and any Compact Flash-compliant device.

Formica Compact Grade high pressure laminate is a high performance, versatile, homogeneous material, much thicker than conventional laminate and generally with a decorative surface on both sides. Compact Grade (also known as solid grade) is an impressively strong and damage-resistant material with excellent dimensional stability and mechanical strength. It is frequently used to manufacture lockers, cubicles and wall panels in high traffic or wet areas in public buildings.

A compact fluorescent is often used as an alternative to a standard light bulb. Compact fluorescents (also called PL twin-tube CFL twist tube or BIAX lamps) can be used in table lamps wall fixtures and lamp posts. The lamp life is about 10 times longer than a standard light bulb and uses 3 to 4 times less energy to operate. Compact fluorescent lamps have a different base (depending on wattage) to reduce the likelihood of using the incorrect ballast.

National Instruments Compact FieldPoint is an easy-to-use, highly expandable industrial control and measurement system composed of rugged and dependable I/O modules and intelligent communication interfaces. Download your LabVIEW application to the embedded controller for reliable, stand-alone operation and connect your sensors directly to high-accuracy analog and discrete I/O modules.

The Compact would come into existence when two states enact the compact model act. The Compact would become operational when 26 states or states representing 40 percent of the premium volume for life insurance, annuities, disability income and long-term care insurance join the Compact.

Both the Lesson Book and Performance Book for each level includes a Compact Disc. Each CD includes two performances of each piece on acoustic piano—a performance tempo and a slower practice tempo.

The Afghanistan Compact marks the formal end of the Bonn Process, with completion of the Parliamentary and Provincial elections, and will establish an effective mechanism for coordinating Afghan and international efforts over the next period. The Afghanistan Compact is the result of consultation between the Government of Afghanistan, the United Nations and the international community, and represents a framework for co-operation for five years. The Compact was launched on 31 January 2006.

Compaction should be performed monthly, or when large amounts of data have been removed or system changes have been performed in the database source code. Note: When forms are opened in the source code, Access allows the maximum space you might need. Because of this you will notice your database growing in size. Compaction will remove the "empty space" from the system.

Compact shelving looks much like standard library shelving however, the shelving is mounted on carriages that move along tracks. The rows of shelves can be pushed together eliminating the aisle between--this allows about twice as many books to be fit into a given space. To allow access to the books, an aisle is created by sliding the shelves apart. The compact shelving in Olin Library is set up in multi-row modules. Only one aisle in each module opens at any one time.

Compact fluorescents are the latest technological advancement in single-ended fluorescent tubes. These tubes contain enriched rare earth phosphors that produce maximum light output while being very energy efficient.

Millions of California voters as well as thousands of civic, law enforcement, academic, business and government leaders and organizations throughout the state support tribal gaming A broad coalition of Californians including business leaders, organized labor, environmental groups, non-profits, community organizations, firefighters, law enforcement and health professionals support the passage of the tribal-state gaming compacts because they know California can used the millions in new revenue to .

Yes - almost. Just don't use them with a dimmer switch or a touch-on lamp. It would burn out the ballast. Also, they can't be used outside because the ballast would get too cold to start the light.
