This LTD 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 0.3mrad.
Without TEC , the entire device can operate within an ambient temperature range from -40℃ to 35℃.
It can achieve illumination for 60s with a 30s interval, continuously cycling for 6 periods; or illumination for 45s with a 30s interval for 2 periods from 35℃ to 50℃.
It is compatible with various combat platforms EO pods, enabling continuous ranging and periodic illumination on targets.
It is a crucial laser device for implementing laser semi-active guidance process.
