Source summary
Indigenously develop and manufacture the Nd:YAG radiator block used for ranging in the T-90 gunner sight's range-finder module. The source requires high-purity crystal growth, precision machining, optical finishing and anti-reflective coating, with stable laser output, beam quality and long life despite high optical energy, thermal stress, vibration and shock. Weapon-employment details are intentionally omitted.
