Radial or angular polarized light laser device based on optical parameter chirped pulse amplification

The invention provides a radial or angular polarized light laser device based on optical parameter chirped pulse amplification. The device is characterized in that picosecond laser is used as a pumping source, radial or angular polarized light is used as a seed source, the picosecond laser and the radial or angular polarized light are respectively divided into two beams by beam splitting sheets, the two beams are combined and then input into a nonlinear amplification crystal to obtain two beams of high-energy partial radial or angular polarized light, and after the two beams of high-energy partial radial or angular polarized light respectively pass through a compressor, one beam of high-energy partial radial or angular polarized light rotated and polarized by 90 DEG by using a half-wave plate and the other beam of high-energy non-uniform femtosecond radial or angular polarized light are combined through a beam combiner. According to the invention, two paths of radial or angular polarized light are amplified b
