| Abstract(in English) | We develop chirped pulse amplification (CPA) system that consists of a femtosecond Ti:sapphire oscillator, an all reflective pulse stretcher, a regenerative amplifier and a PC controllable Tracy compressor. The compressor consists of two stepping motors and two PZT to control the distance and the angle. Using the feedback system With the compressor and the autocorrelator, we can control the pulsewidth from 50 fs to 1 ps. We also present a new method in which not only the system can be initialized but also the pulse shape can be controlled using the spectral phase measured with the spectral phase interferometry for direct electric-field reconstruction (SPIDER). |
