SELF-COLLIMATOR PLANAR SPECTROSCOPY SHAPING DEVICE FOR CHIRPED-PULSE-AMPLIFICAITION

摘要

A self-collimator planar spectroscopy shaping device for chirped pulse amplification (CPA) comprises a CTSI spectral decomposition system and a CTSI spectral synthesizing system being self-collimation, and a spectral modulating system composed of a diaphragm (10) and a plane spectra modulating reflector (5), wherein the CTSI spectral decomposition system totally expands a laser chirped pulse to a spectra plane, the spectral modulating system performs a spectra modulation on the image plane, and the CTSI spectral synthesizing system reverts the modulated spectra into the chirped pulse without distortion, thereby realizing spectra shaping.
