Аннотация:A method for optical pump scheme optimization for a laser gain module with pulsed diode
arrays for Nd:YAG rods (Ø10 × 130 mm & Ø10 × 160 mm) is presented. The goal is to
maximize the small-signal gain of the laser gain module while maintaining a flat-top
amplification profile. A possible way of the overall small-signal gain reduction due to amplified
spontaneous emission is discussed and a method to deal with this phenomenon is given. As a
result of optical pump scheme optimization, the gain module with the maximum pump power of
40 kW for 250 μs pulse duration at repetition rates of up to 25 Hz is created. The maximum
small-signal gain G = 100 at 1.064 μm is achieved.
