High power, repetitively pulsed Cr:LiSAF thin slab zig-zag power oscillator

Summary form only given. We have been developing a high energy per pulse, high power Cr:LiSAF laser for an unconventional imaging application. The final ground based transmitter device is envisioned to consist of three, 30 J beams with a beam quality <1.5 XDL, operating at a wavelength that is matched to the Cs atomic filter line (852 nm), and with a bandwidth of 2 GHz. This device is to operate at repetition rates of at least 5 Hz. A single oscillator-preamplifier subsystem will inject three, multi-stage amplifier chains made up of a number of similar Cr:LiSAF zig-zag laser modules.
