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

Description

Technical field [0001] The invention belongs to the technical field of laser heat dissipation, and specifically relates to a heat dissipation device and method for combining the end face and the side face of a round rod-shaped laser crystal. Background technique [0002] In recent years, diode solid-state lasers have been widely used in industries, medical, military, scientific research, and aerospace. However, the development of diode-pumped solid-state lasers is still limited by many factors, and the thermal effect of laser crystals is one of them. Traditional diode end-pumped solid-state lasers usually use round rod-shaped laser crystals as working materials. 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 to conduct heat dissipation. Conductive heat dissipation has many advantages such as full curing and stable s...
