We have developed a high-energy, ultrabroadband Ti:sapphire ring regenerative amplifier capable of producing in excess of 20mJ output at a 10Hz repetition rate. The technique of chirped-pulse amplification is used to generate two-color, time-synchronized pulses, with central wavelength separations up to 
120nm and with a total energy of 10mJ by using a regenerative pulse shaping technique.

A practical CPA laser has been developed using the chirp-reversal of an idler pulse generating in OPA scheme. We have made a new monolithic glass block for both pulse stretching and compressing in CPA, which is 10-times smaller than previous one. In the experiment, sub-100 fs compressed pulse was generated using the glass block.
