High power, high beam quality solid state lasers for materials processing applications

Abstract

The Laser Science and Technology Department at Lawrence Livermore National Laboratory is developing solid state lasers with high average power and high beam quality. Specific systems include a laser to generate 10 to 14 A x-rays for proximity print lithography, a 400 mJ, 500 Hz laser for 130 A projection lithography and unique systems for speckle imaging, laser radars and medical treatments.The Laser Science and Technology Department at Lawrence Livermore National Laboratory is developing solid state lasers with high average power and high beam quality.
