Problems solved by technology

It can be seen that this technology moves the bottleneck of power improvement from the amplifier to the grating compressor. Since the grating compressor has to withstand extremely high laser power, it is easy to cause component damage
This is also the core reason why it is difficult for the above-mentioned large-scale devices to improve laser performance

Abstract

The invention discloses a subtend compression chirped pulse amplification laser system, comprising a seed source, a stretcher, a subtend compressor and a focusing mirror; the subtend compressor consists of a raster compressor, two polarizing beam-splitter plates, two polarization converters, one delayer and five reflectors. The subtend compression chirped pulse amplification laser system realizes the two-way time-sharing secondary utilization of the raster compressor, breaks through the limitation of the bearing capacity of the taster compressor, avoids the non-linear effect, has the identical dispersion compression amount and realizes multiplication of the output capability of the chirped pulse amplification laser system.

Description

technical field [0001] The invention relates to the field of lasers, in particular to a chirped pulse amplification laser system, which is mainly suitable for performance improvement of high-energy, high-power ultra-short and ultra-intense laser systems. Background technique [0002] At present, high-energy and high-power ultra-short and ultra-intense laser is the focus and hotspot of laser technology research in the world. The birth of chirped pulse amplification technology in 1985 made the laser power and power density available to humans break through GW (10 9 W) and 10 15 W / cm 2 , and in the following 30 years, this technology made the laser power and power density break through TW (10 12 W) and 10 18 W / cm 2 , and PW (10 15 W) and 10 20 W / cm 2 . The development of this laser technology has greatly promoted the research of basic physics, and created unprecedented conditions for human beings to explore the origin of matter, the unknown universe and energy issues. ...
