Product Description

Product Description

349nm passively Q-switched Laser with TEC cooling system mainly consists of five parts: working material, pumping system, concentrating system, optical resonator, cooling and filtering. 349nm passively Q-switched Laser with TEC cooling system has higher peak power and average power, lower energy consumption, excellent pulse energy and excellent beam quality, easy to maintain and can work for a long time. In addition, the laser gives full play to the advantages of solid state technology, with compact structure, good performance, long service life, good frequency stability, small thermal light distortion and high pumping efficiency. And the laser is widely used in DNA sequencing,Micro-electronics,Cell sorting.
