Intracavity acousto-optic programmable gain control for ultra-wide-band regenerative amplifiers

Abstract

We have developed a new Brewster-cut acousto-optic programmable gain control filter to optimize the spectral losses inside a regenerative cavity. This spectral amplitude control combined with an acousto-optic programmable dispersive filter for the spectral phase control optimizes, in a few steps of a direct algorithm, the performance of a 10-Hz CPA Ti:sapphire laser to 18-fs pulse duration, 1.2% RMS energy stability and 107 contrast ratio.
