Abstract
A spectra shaping apparatus for chirped pulse amplification(CPA) comprises a CTSI spectral decomposition system and a CTSI spectral synthesizing system being symmetrical, 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. The apparatus has the feature of manufacturing easy, compacting structure, requiring less space, and cheap in cost etc., which can be different types of configuration for different circumstance application, and which can be utilized in a general laser spectrum shaping and spectrum modulation, especially for a high energy and ultra-high peak-power laser system with a large caliber and a broadband of pulse.
