Claim:
A self-collimator planar spectroscopy shaping device for chirped pulse amplification (CPA): of which the features are the comprising in the optical path order: the first beam splitter prism ( 8 ), the second beam splitter prism ( 9 ), and the ¼ wave plate ( 7 ); and the first concave reflector ( 1 ), the first aperture ( 6 ), and the second concave reflector ( 2 ), which these ( 1 )-( 6 )-( 2 ) constitute a illumination system; and, the first aperture ( 6 ), the second concave reflector ( 2 ), the grating ( 3 ), the third concave reflector ( 4 ) and the second aperture ( 10 ), which these ( 6 )-( 2 )-( 3 )-( 4 )-( 10 ) constitute a spectrum decomposing system for the self-collimator planar spectroscopy shaping device; in addition, the second aperture ( 10 ) and the planar reflector for spectrum shaping function design ( 5 ) that is at the same place with the second aperture, which these ( 10 )-( 5 ) constitute a spectrum shaping system; furthermore, the centro-symmetric concave reflector ( 4 ″), the second aperture ( 10 ) and the planar reflector for spectrum shaping function design ( 5 ) that is at the same place with the second aperture, the third concave reflector ( 4 ), the grating ( 3 ), the second concave reflector ( 2 ), and the first aperture ( 6 ), which these ( 4 ″)-( 10 )-( 5 )-( 4 )-( 3 )-( 2 )-( 6 ) constitute a spectrum synthesizing system for the self-collimator planar spectroscopy shaping device; of which the features are the processing: a laser beam from the front-end system ( 0 ) of a CPA system passes through the first beam splitter prism for polarization producing; via the ¼ wave plate and the first concave reflector, then it passes through the first concave reflector, which transferring the laser beam into a parallel light; As mentioned above, it passes through the spectrum decomposing system, the spectrum shaping system and the spectrum synthesizing system for the self-collimator planar spectroscopy shaping device, which accomplish the spectrum decomposing, the spectrum shaping, and the spectrum synthesizing of the chirped pulse; then it passes through the ¼ wave plate, its polarization rotates 90 degree; then it is reflected fully by the first beam splitter prism to the second beam splitter prism for a polarization producing of the modulated chirped pulse, and sent into the following stage such as the solid-state amplifier ( 0 ′) for amplification.
