Generation of high-power, high repetition rate, subpicosecond pulses by intracavity chirped pulse regenerative amplification

Abstract

A neodymium phosphate glass regenerative amplifier is used for both pulse energy amplification and spectral broadening. After compression by a grating pair, 0.55 ps pulses of 11 μJ energy are generated at a 370 Hz repetition rate.

Compression of picosecond light pulses of a hybridly mode-locked pulsed Nd : glass laser

“…5.3± I ps) we achieved a compression down to 0.7±0.3 ps. The compression of pulses of a cw mode-locked and regenerative amplified Nd:phosphate glass laser has been reported earlier [40,41]. In this case self-phase modulation occurred in the regenerative amplifier.…”
