Abstract

The invention relates to a light gathering cavity of a lamp pump laser and the lamp pump laser, and belongs to the technical field of lasers, the light gathering cavity comprises a ceramic cavity body, a cavity is formed in the ceramic cavity body, a xenon lamp and a laser crystal are arranged in the cavity, and a samarium-doped glass tube covers the laser crystal; the inner wall of the cavity of the ceramic cavity body is coated with a samarium-doped glaze layer; the xenon lamp irradiates the laser crystal to excite the laser crystal to emit light with the wavelength of 1064nm, and the light with the wavelength of 1064nm penetrates through the samarium-doped glass tube and is reflected in the cavity for multiple times through the samarium-doped glaze layer; wherein when the light rays with the wavelength of 1064nm penetrate through the samarium-doped glass tube every time, part of the light rays with the wavelength of 1064nm are absorbed by the samarium-doped glass tube; and when the light with the wavelength of 1064nm passes through the samarium-doped glaze layer to be reflected every time, part of the light with the wavelength of 1064nm is absorbed by the samarium-doped glaze layer. The effect of improving the electro-optical efficiency of the ceramic cavity is achieved.

Description

technical field [0001] The present application relates to the field of lasers, in particular to a light-collecting cavity of a lamp-pumped laser and the lamp-pumped laser. Background technique [0002] The high-energy solid-state laser pumped by the flash lamp is a special laser for scientific research and industry. This type of laser can output nanosecond laser pulses > 10J, and the repetition rate is generally < 20Hz. It is usually used in laser shock strengthening, laser plasma research, Laser damage threshold research, titanium sapphire laser pump source, laser annealing and other fields. [0003] At present, lamp-pumped lasers usually use xenon lamps (hereinafter referred to as "xenon lamps") to excite Nd:YAG laser crystals to emit light. [0004] Xenon lamp has the characteristics of high luminous energy and emission spectrum matching the absorption spectrum of Nd:YAG laser crystal, so it is widely used as a pump source for high-energy laser pulses. Nd:YAG lase...
