Laser energy absorption and subsequent heat removal from diffraction gratings in chirped pulse compressors poses a significant challenge in high repetition rate, high peak power laser development. In order to understand the average power limitations,

We have developed a high-efficiency (∼90%), broad-bandwidth low-absorption pulse compressor suitable for high energy pulses. This technology is a significant step in enabling high peak power laser systems to operate at high repetition rates.

We have developed improved cavity-finesse methods for characterizing the diffraction efficiencies of large gratings at the Littrow angle. These methods include measuring cavity length with optical techniques, using a Michelson interferometer to calib

We describe the design, fabrication, and test of large-area multilayer dielectric gratings for high-energy petawatt lasers. 80/spl times/40-cm/sup 2/, 1780-mm/sup -1/ gratings have been fabricated, exhibiting high diffraction efficiency and >4 J/cm/s

To enable high-energy petawatt laser operation we have developed the processing methods and tooling that produced both the world's largest multilayer dielectric reflection grating and the world's highest laser damage resistant gratings. We have succe

This FY03 final report on Wet Etch Figuring involves a 2D thermal tool. Its purpose is to flatten (0.3 to 1 mm thickness) sheets of glass faster thus cheaper than conventional sub aperture tools. An array of resistors on a circuit board was used to h

Reflective diffraction gratings enable novel optical configurations that simplify and improve laser interferometers. We have proposed an all-reflective grating interferometer that can be used in LISA type interferometers for space gravitational wave

Wet-etch figuring utilizes free surface flows driven by surface tension gradients (the Marangoni effect) to confine and stabilize the size and shape of an etchant droplet attached to the underside of a glass surface. This droplet, or wetted zone, is

Presently, modeling techniques have been established for radio frequency interference prediction in search radars. Modeling techniques for the special group of radars, classified as tracking radars, are relatively new and require further development
