Abstract

TEWALAS facility consists in a Ti:sapphire laser system based on chirped pulse amplification. Oscillator femtosecond pulses, after passing through a booster and intensity contrast improvement module, are stretched up to 300 ps. The stretched pulses are amplified by a regenerative amplifier, two multi-pass amplifiers and re-compressed in a vacuum compressor. More than 109 intensity contrast of femtosecond pulses in relation to the amplified spontaneous emission was obtained. Amplified laser pulses, with as much as 440 mJ pulse energy, are compressed down to 23 fs at 10 Hz repetition rate..

Keywords
