Abstract

The invention discloses a pumping ring cavity regenerative amplifier. Seed light transmitted by a mode locking oscillator is reflected to an electric light potassium dihydrogen phosphate crystal through a first thin film polarizing film, the electric light potassium dihydrogen phosphate crystal directly transmits the seed light to a second thin film polarizing film without adding voltages, then one half voltages are applied to polarized light to enable the polarizing direction perpendicularly penetrating through the polarized light to be rotated at 90 degrees, and when the energy of the polarized light reaches the maximum, voltage supply is ended, the polarized light is output, processing is carried out on the polarized light through the second thin film polarizing film, a first plane reflecting mirror, a yttrium aluminum garnet crystal bar, a one-half wave plate, a second plane reflecting mirror and a third plane reflecting mirror in sequence, the regenerative seed light will not be returned along a seed light transmission light path, and stability of the regenerative light is effectively improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a regenerative amplifier for a pumped ring cavity. Background technique [0002] In order to obtain higher peak power and greater single-pulse energy, it is necessary to perform optical amplification on the seed light, and the commonly used amplification methods include single-pass, multi-pass and regenerative amplification. At present, the regenerative amplifier is a stable resonant cavity, which can ensure that the seed light and the pump light are completely collinearly coupled, increasing the amplification efficiency and outputting a good beam quality. [0003] At present, the regenerative amplifier seed light import method and regenerative light export method commonly used in the industry are as follows: figure 1 As shown, it includes a first polarizer 101 , a half wave plate 102 , a Faraday isolator 103 and a second polarizer 104 . During the regenerative amplificat...
