Abstract

The invention provides a chirped pulse compression device and a laser. The chirped pulse compression device comprises the following components: a translation roof prism and a grating which are spaced oppositely, wherein all angles are arranged in a total reflection manner; and a reflector assembly which comprises a plurality of reflectors which are all located between the grating and the translation roof prism; wherein after incident light is emitted to the grating, the incident light is diffracted by the grating to form first light which is emitted to the reflector assembly along a first direction, and the first light is reflected back to the reflector assembly after being reflected by the reflector assembly for multiple times and translated by the reference surface position of the translational roof prism, and then is reflected for many times; and the light returns and enters the grating along the direction symmetrical with the first direction relative to the normal direction, and then is subjected to secondary diffraction by the grating to form a second light meeting the grating diffraction condition. The chirped pulse compression device provided by the invention can improve the utilization rate of the grating region and increase the compressible pulse width so as to improve the pulse output single pulse energy and reduce the cost.

Description

technical field [0001] This application belongs to the technical field of laser devices, and more specifically relates to a chirped pulse compression device and a laser. Background technique [0002] At present, ultrafast lasers with high power and high pulse energy reaching the femtosecond or picosecond level are widely used in precision micromachining, biomedical and scientific research fields due to their narrow pulse width, large single pulse energy, and high repetition rate. . In order to obtain ultrafast lasers with high power and large pulse energy, chirped pulse amplification technology (Chirped Pulse Amplification, CPA) is usually used in the industry. This technology first expands the seed pulse width to the level of hundreds of picoseconds or nanoseconds, increases the average power through the amplification stage, and then further compresses the pulse width to the level of femtoseconds or picoseconds through the chirped pulse compression device. Here, the exten...
