Paper Abstract

Progress on developing a multiterrawatt source of pulses with duration <100 fsec is described. The laser system is based on chirped-pulse amplification in titanium-doped sapphire. Experimental results include the development of a stable oscillator running at 812 nm, using hybrid mode-locking and compressed pulse pumping to produce <60 fsec pulses. Two methods of active stabilization are used to produce reliable output. In addition, high-gain preamplification in Ti:sapphire has been demonstrated, using a high-quality pump beam to produce gains of 130 per pass, and -10,000 in a simple double-pass gain configuration, while avoiding crystal damage problems. Finally, grating pulse stretching and recompression from 60 fsec to ..3øø p and back down to 140 fsec has been demonstrated at low power.
