“…The optical pump consists of 20 laser diode arrays (LDAs) produced by Scientific Production Enterprise «Inject», which were combined into five channels with four LDAs in each. Thus, a five-side transverse diode pump of the Nd:YAG rod is realized (similar to [3,11]). The radiation size area of a single LDA is 24 × 5 mm, each array consisting of 50 diodes.…”

“…Recent development of semiconductor lasers production technology has led to creation of high-power single-bar diode lasers combined into arrays with reasonable cost, which allow a production of high-efficient high-power (in order of tens of kW) pump systems for solid-state lasers [1]. Transverse diode pumping is usually used in the gain modules of high-power lasers and amplifiers with active media element formed as a cylindrical rod or a plate [2][3][4][5]. Depending on the application, different requirements on the stored energy profile are to be met during a gain module design.…”

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.
