Solid laser array amplifier

Abstract

The invention discloses a solid laser array amplifier, and the array amplifier comprises a body shell, an isolation end, a water guide end, a rod sleeve, a crystal adjustable unit, a lamp pressing plate and a unit matching structure. An upper-layer pumping coupling cavity and a lower-layer pumping coupling cavity are arranged in the body shell, and two crystal bars and three xenon lamps are arranged in each pumping coupling cavity at equal intervals, so the laser amplifier can amplify a plurality of laser beams at the same time. A xenon lamp is fixed through a lamp pressing plate, rod sleeves are installed at the two ends of a crystal rod, a crystal is installed in an amplifier through a micro-adjustment assembly of a crystal adjustable unit, and the crystal rod has the radial adjustable range of + / -0.5 mm to + / -1.5 mm by means of the elasticity of an inner rubber gasket and an outer rubber gasket. The solid laser array amplifier solves the problems that an existing laser amplifier is difficult to amplify a multi-beam laser array and the position of a crystal rod cannot be adjusted. The solid laser array amplifier can be applied to a high-power laser nonlinear beam combination technology.

Description

technical field [0001] The invention relates to the field of amplifiers, in particular to a solid-state laser array amplifier. Background technique [0002] Solid-state laser amplifiers have the advantages of high brightness, high efficiency, compact structure, and stable performance, and have important applications in many fields. With the development of laser application technology, high-power, high-quality and high-brightness laser beams have important applications in lidar and other fields, and lasers are developing in the direction of miniaturization and full solid-state. Compared with a single laser, laser array amplifiers can obtain higher output power, so the development of solid-state laser array amplifiers is particularly important. [0003] Although the output light of the existing laser amplifier array can meet high power requirements, it still has the following disadvantages: [0004] Most of the existing amplifiers have a structure in which one crystal rod is...
