Problems solved by technology

At the same time, for end-pumped solid-state lasers, the heat consumption is mainly concentrated near the end of the crystal, which will cause the temperature of the end of the crystal to be too high, and serious thermal lens effect will occur, which will affect the quality of the output beam.
When the heat loss increases and the heat dissipation is uneven, the crystal will burst due to uneven heating

Abstract

The invention discloses a circular-rod-shaped laser crystal end face and side face combination radiating device which comprises a heat sink block, a side face compact radiating component and an end face compact radiating component. The side face compact radiating component comprises a crystal clamping component, a side face fastening bolt and a metal gasket. A first light through hole and a first hexagon screw hole are formed in the side face fastening bolt. The end face compact radiating component comprises a transparent diamond circular table, a diamond fastening piece and an end face fastening bolt. The diamond fastening piece is provided with a diamond circular table mounting hole and a second light through hole. The end face fastening bolt is provided with a third thread hole and a second hexagon screw hole. The heat sink block is provided with a circular-table-shaped through hole, a first thread hole, a cylinder hole and a second thread hole.

Circular-rod-shaped laser crystal inner heat load can be lowered, laser output power can be improved to the maximum degree, light beam quality is improved, and crystal bursting is avoided.

Description

technical field [0001] The invention belongs to the technical field of laser heat dissipation, and in particular relates to a combined heat dissipation device and method for a round rod-shaped laser crystal end face and side face. Background technique [0002] In recent years, diode solid-state lasers have been widely used in fields such as industry, medical treatment, military affairs, scientific research, and aerospace. However, the development of diode-pumped solid-state lasers is still limited by many factors, one of which is the thermal effect of laser crystals. Traditional diode end-pumped solid-state lasers usually use round rod-shaped laser crystals as working substances. For the heat dissipation of the crystal rod, two metal heat sinks with semicircular grooves are generally used to clamp, and the contact between the relatively large side of the crystal and the heat sink is used for conduction and heat dissipation. Conduction heat dissipation has many advantages s...
