• LS-2138N, LS-2138TF, LS-2138N/5, LS-2138N-100, LS-2138TF-100


The LS-2138 incorporates all advantages of LS-2136 and LS-2137 lasers with a pulse repetition rate up to 100 Hz, small divergence, output energy up to 220 mJ.

The double rod laser chamber and rigid folded laser resonator with intracavity telescope work together to create stable, reliable, and highly efficient operation. A single power supply and self-contained cooling unit with water-to-air heat exchanger are used in LS-2138.

LS-2138OPO – is high energy Q-switched Nd:YAG laser with built-in eye-safe (1577nm) OPO converter that design for LIDAR application. Special ring cavity design with two KTP crystals (cut for non-critical type II phase matching NCPM) provides output energy 35 mJ (at 1577 nm) with pulse repetition rate up to 50 Hz.

LS-2138TF – improved LS-2138 model with built-in third and forth harmonics.

All laser functions are controlled via a compact remote control and external triggering and synchronization are supported. The remote features a scrolling menu with an adjusting thumbwheel, high visibility LCD and audible tone to indicate changed settings.
