Abstract

With the advent of high-power laser pump diodes, significant reductions in solid state laser system weight and size are possible due to the efficient coupling of electrical to optical energy. Typical electrical conversion efficiencies for laser diode arrays are 45% for operation up to 20% duty cycle regime. The substantial saving in system weight and size is not primarily due to reductions in the pump module, but rather in the size of power supplies and cooling equipment. Used in conjunction with a Nd:YAG zig-zag slab configuration, diode array pumping allows for simple heat removal and uniform excitation of the gain region. In this paper we will discuss the performance of a compact zig-zag slab laser designed to operate in rugged military or space environments. The laser is air cooled, battering powered and designed to be man-portable with a total weight of 7.5 kg. The frequency doubled output energy at 532 nm is 270 mJ per pulse at 10 PPS.
