1064nm Laser Ranging Target Designator 20km
DESCRIPTION
The LDR80K2-02 Laser Designator adopts a transceiver co-aperture lens. It uses an LDA-pumped Nd: YAG crystal combined with an electro-optical Q-switching technology solution to achieve a typical 1064nm pulsed laser output. The single-pulse energy is 80 mJ, and the beam divergence angle is 0.25mrad. It employs an adaptive non-temperature-control technology, allowing it to start working immediately. The entire device can operate for 90 seconds, pause for 60 seconds within Man ambient temperature range of -40°C to 60°C; 4 cycles (at normal or low temperatures); 1 cycle (at a high temperature of 60°C). It can be compatibly installed and applied in miniaturized electro-optical pods on airborne platforms, loitering munitions, and other combat platforms, realizing continuous ranging and periodic illumination of targets. It is an important laser device in the implementation of semi-active systems.
