摘要：

The tilt of the pulse front caused by misalignment in stretcher-compressor devices which are used in chirped pulse amplification should be carefully considered in the design of femtosecond laser systems. We present a convenient procedure for online measurement and minimization of the tilt in a grating stretcher/compressor setup. In addition, we present a theoretical model for the autocorrelation signal in the presence of pulse front distortion. The influence of the pulse front tilt to the autocorrelation function is numerically simulated and compared with the case for pulses with fourth order chirp.
