A High Repetition Frequency Free Temperature Control Diode Pumped 1064nm Disk Laser

Abstract

The invention provides a high-repetition-frequency temperature-free semiconductor-pumped 1064nm disk laser. Compared with the existing similar equipment, the laser does not need any forced cooling measures. During operation, the pump light generated by the LD tube is output to the laser resonator formed by the laser medium and the Q-switched crystal after passing through the coupling lens. The output of the protective mirror realizes the pulsed laser output. The laser occupies a small space, provides stable and good 1064nm laser output performance, has the advantages of low power consumption, small beam divergence, and simple and convenient debugging. Adjustment, the whole set of equipment can realize no-temperature control and high repetition frequency when starting up in the temperature range of -40°C to 55°C.

Description

technical field [0001] The invention relates to the technical field of solid-state lasers, in particular to a high-repetition-frequency temperature-control-free semiconductor-pumped 1064nm disk laser. Background technique [0002] Solid-state lasers are widely used in military and civilian technology fields such as laser ranging, laser irradiation, and imaging, and their development direction is miniaturization, integration, and lightweight. Existing 1064nm solid-state lasers generally adopt a lamp-pump concentrator or a semiconductor side-pump structure of a temperature control system. Although this type of solid-state laser has a high output energy, it is often large in size and weight, and it is difficult to meet the user's requirements for lightweight and portable equipment. requirements. In addition, the laser frequency generated by the semiconductor side pump of the temperature control system is low (generally below 25Hz), and the start-up work requires a long prepara...

Problems solved by technology

Existing 1064nm solid-state lasers generally adopt a lamp-pump concentrator or a semiconductor side-pump structure of a temperature control system. Although this type of solid-state laser has a high output energy, it is often large in size and weight, and it is difficult to meet the user's requirements for lightweight and portable equipment. requirements

In addition, the laser frequency generated by the semiconductor side pump of the temperature control system is low (generally below 25Hz), and the start-up work requires a long preparation time, which is difficult to meet the user's requirements for fast tracking and observation of moving targets and start-up work

More importantly, the existing solid-state lasers have poor heat dissipation, and the serious heat accumulation leads to short continuous working time of the equipment, which often requires additional cooling or heat dissipation systems (such as Chinese patents CN201528122U, CN207530300U, etc.), which will undoubtedly increase equipment production costs and Manufacturing complexity will also have a certain impact on system stability and reliability
