Abstract
Analytical phase expressions are presented for an Offner stretcher and transmission grating compressor based on ray tracing and apply them to analyze a chirped-pulse-amplification (CPA) system. Besides, an optimization method to extract high-fidelity amplified pulse is proposed by controlling the phase of the entire system. Through theoretical analysis and numerical simulation, one can adjust the incident angle and perpendicular distance between gratings to completely compensate dispersion of Offner stretcher over entire wavelength. Finally, the optimized CPA system provides Fourier-transform-limit pulse which is identical with seed pulse.
