Xenon lamp-pumped liquid cooling laminated repetition frequency sheet amplifier

Abstract

The invention discloses a xenon lamp-pumped liquid cooling laminated repetition frequency sheet amplifier. The xenon lamp-pumped liquid cooling laminated repetition frequency sheet amplifier comprisesa lamp box assembly, a sheet frame assembly, a sheet cavity assembly and an end mirror assembly, and is characterized in that the included angle theta of the sheet frame assembly and the light transmission direction is 45 degrees for installation; the sheet frame assembly is installed inside the sheet cavity assembly from top to bottom; the lower bottom surface of the sheet frame is overlapped with the upper surface of the lower base plate of the sheet cavity; the lamp box assembly is installed on the left and right sides of the sheet cavity assembly in virtue of screw dislocation; and the end mirror assembly is centrally dislocated along the light transmission direction and is installed on the front and rear sides of the sheet cavity assembly in virtue of screws. The spontaneous radiation of the amplifier is reduced effectively by using end mirror inclination swing, xenon lamp liquid cooling, gain medium laminated liquid guide uniform cooling and sheet box air-cool clean control, theparasitic oscillation is inhibited, the energy storage efficiency and heat management are improved, and the repetition frequency sheet amplifier has the characteristics of high efficiency, high repletion frequency, low cost, high energy, high gain uniformity and stable operation.

Description

technical field [0001] The invention relates to a high-power solid-state laser, in particular to a liquid-cooled laminated repetition rate chip amplifier pumped by a xenon lamp. Background technique [0002] In the 21st century, energy issues and regional conflicts have become increasingly prominent, and it is particularly important to accelerate the development of new energy sources and consolidate national defense. Because the controlled nuclear fusion technology can release the huge energy in the nucleus, and the fusion raw material comes from the inexhaustible seawater, this technology is expected to completely solve the energy problems faced by human beings, but it is necessary to realize laser fusion energy The laser energy needs to reach 2.5MJ, and the shooting frequency should be above 10Hz. Therefore, with the traction of fusion energy engineering (IFE) solid-state laser drivers, lasers are gradually developing in the direction of high energy and high repetition fre...

Problems solved by technology

Although the above thermal effects and compensation techniques have achieved certain results, but: (1) Most of the amplifying media use Yb:YAG crystals that are difficult to provide with large sizes, and the light aperture is small; (2) In order to reduce the working threshold, Yb:YAG The crystal works in a four-level state, which must be kept at a low temperature of 170K; (3) the pump source is limited to the still expensive laser diode
