It employs an LDA-pumped Nd:YAG crystal combined with an electro-optic Q-switching technology, to achieve a typical 1064nm pulsed laser output with a single pulse energy of 45mJ, and a beam divergence angle of 0.5mrad.
Utilizing TEC temperature control technology, the entire device can operate within an ambient temperature range from -40℃ to 60℃. It can achieve illumination for 47s with a 30s interval, continuously cycling for 2 periods; or illumination for 20s with a 30s interval for 10 periods.
It is compatible with various combat platforms EO pods, particularly suitable for miniaturized airborne EO pods, enabling continuous ranging and periodic illumination on targets.
It is a crucial laser device for implementing laser semi-active guidance process.
