Device and method for improving working frequency of lamp pump laser amplifiers

Abstract

The invention relates to a device for improving working frequency of lamp pump laser amplifiers. The device comprises a plurality of lamp pump laser amplifiers, a fixed reflection mirror and a rotary reflection mirror, wherein the rotary reflection mirror is in light connection with the fixed reflection mirror by rotation; the rotary reflection mirror receives input light, and reflects the light to the fixed reflection mirror by rotation; the fixed reflection mirror is located in front of the lamp pump laser amplifiers; the fixed reflection mirror receives the reflected light from the rotary reflection mirror, and reflects the light to a corresponding lamp pump laser amplifier; and by the matching of the rotary reflection mirror and the fixed reflection mirror, the laser sequentially enters the plurality of lamp pump laser amplifiers so as to improve the working frequency. According to the device and method provided by the invention, the lamp pump laser amplifiers can be moved without complicated mechanical design and ponderous rotating wheel type devices like the traditional method, thus the mechanical design is simplified, mechanical devices are reduced, the occupied space of the integral device is small, and the cost is lowered due to reduction of mechanical material use.

Description

technical field [0001] The invention relates to the field of laser amplifiers, in particular to a device for increasing the operating frequency of a lamp pump laser amplifier. Background technique [0002] The lamp-pumped laser amplifier cannot work at the repetition frequency, that is, after working once, it needs to wait for a certain period of time before it can work again. Its operating frequency is relatively small. One way to increase the operating frequency of a lamp-pump laser amplifier is to combine multiple lamp-pump laser amplifiers to use them in turn. For example, if the operating frequency of a single lamp-pump laser amplifier is 1 / 20min -1 , that is, you need to wait for 20 minutes for each work, and by combining 4 lamp pump laser amplifiers to make them work in sequence, the working frequency will increase by 1 / 5min -1 , just wait 5 minutes to make the lamp pump laser amplifier work once. In the traditional method, a plurality of lamp-pump laser amplifiers ...

AI Technical Summary

Problems solved by technology

Due to the large size and heavy weight of the lamp-pumped laser amplifier, and in order to meet the needs of the actual frequency of use, the traditional method requires complex mechanical design and a bulky rotary device. The overall device occupies a large space and is expensive, which is not conducive to operation.
