Patent ID: 8908739

Claim:
A laser system, comprising: an oscillator, configured to generate a seed beam; a stretcher-compressor, configured to receive the seed beam, and to stretch a duration of seed pulses of the seed beam; an adjustable seed-beam restrictor attached in a transverse-adjustable manner to a stretcher face of the stretcher-compressor, and configured to restrict an incidence of the seed beam, generated by the oscillator on the stretcher compressor, and an amplifier, configured to receive the stretched seed pulses form the stretcher-compressor, to amplify an amplitude of selected stretched seed pulses to create amplified stretched pules, and to output a laser beam of amplified stretched pulses, the stretcher-compressor, configured to receive the laser beam of amplified stretched pulses, to compress a duration of the amplified stretched pulses, and to output a laser beam of compressed pulses, an adjustable amplified-beam restrictor attached in a transverse-adjustable manner to a compressor face of the stretcher-compressor, and configured to restrict an incidence of an amplified beam on the stretcher-compressor.
