Problems solved by technology

[0006] To sum up, although the industry currently adopts various methods to avoid the occurrence of "self-excitation" and plays a key role in the generation of "self-excitation", these methods will cause the optical path to tilt, and in the process of mass production Can't guarantee consistency, so not ideal for avoiding "self-excitation"

Abstract

The invention discloses a device for restraining self-excitation in an image-relaying laser amplifier, which can restrain self-excitation generation in an amplification cavity and comprises a hollow cavity, a first window sheet and a second window sheet respectively installed at two ends of the cavity and a light beam collector arranged in the cavity between the first window sheet and the second window sheet and dividing the cavity into a first cavity and a second cavity. The light beam collector is conical, a small hole is arranged at the top end of the conical light beam collector, and the second cavity is a vacuum cavity. A manufacture method of the device for restraining self-excitation in the image-relaying laser amplifier is further disclosed. The device has the advantages of improving output power of the laser amplifier and ensuring facula model quality.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a device for suppressing self-excitation in a large-energy image transfer laser amplifier system and a manufacturing method thereof. Background technique [0002] At present, in the large-energy traveling-wave amplified laser, it is very necessary to ensure the laser output with high beam quality while ensuring the amplification of the large-energy seed light source. However, due to the large output energy of the traveling-wave amplified laser, in order to To ensure the stable output of the system, under normal conditions, image transfer technology is used in the laser amplification cavity of the laser to expand the laser spot on the optical element, thereby ensuring that all levels of system components work within a stable threshold range. Finally, a stable output is obtained. [0003] However, although the above-mentioned method can obtain a stable output, it still has defects....
