We have been investigating the possibility of ultimate down sizing of the CPA system by improving over all efficiency to convert the green pump energy to the Ti:sapphire wavelength by optimizing the regenerative amplifier. A regenerative amplifier with high gain to achieve small signal and saturated amplification was constructed. By selecting cavity parameters which allow for large gain cross section in the regenerative amplifier we obtained a pulse energy of 13mJ amplified form sub-nanojoule of the seed pulse in 11 round trips. We achieved overall efficiency of 15 percent in single amplifier pumped by single green source.
