Abstract

We demonstrate a large energy output and a wider output spectral bandwidth from Nd:glass-based regenerative amplifiers. The maximum energy extracted from the regenerative amplifier is 24mJ with an overall gain of 3.4×108. The maximum output bandwidth achieved is 4.2nm FWHM when the input pulse spectral bandwidth is 7nm FWHM. This was made possible by a new cavity optimization technique.
