Times Cited Count：5 Percentile：30.58(Optics)We have developed a 1 kHz regenerative amplifier using an Yb:YO ceramic thin disk as the gain medium. Furthermore, the thermal conductivity and heat generation property of Yb: YO ceramic were investigated. In the developed regenerative amplifier, a laser beam is bounced off the thin disk six times in each round trip. The output energy is over 2 mJ, spectral bandwidth is 1.8 nm at FWHM, and pulse duration after pulse compression is 0.9 ps.

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.
