Abstract:

The development of high average power pulsed solid-sta te lasers and the application of these lasers to the generation of laser produced plasmas for soft-x-ray generation is described. A 44-W average power moving slab neodymium glass laser was demonstrated. In a separate experiment, injection seeding of this laser to produce 500-MW ll-ps pulses was attained. Soft-x-ray generation has been investigated with the moving slab laser, a fix slab laser, and commercial rod-geometry lasers. The techniques that were demonstrated show the feasibility of scaling the operation of slab lasers to the kilowatt level. The rapid development of diode-laser pumping techniques suggests the potential for remarkable efficient, compact and economical laser systems for short wavelength lithography and microscopy applications.
