ABSTRACT

We report generation of 1.35 microJ femtosecond laser pulses with a peak power of 3 MW at 1 MHz repetition rate from a diode-pumped Yb:KY(WO4)2 laser oscillator with cavity dumping. By extracavity compression with a large-mode-area fiber and a prism sequence, we generate ultrashort pulses with a duration of 21 fs and a peak power of 13 MW.

ABSTRACT

High speed electro-optical cavity dumping is demonstrated with diode-pumped mode-locked laser oscillators, namely a femtosecond Yb:glass and a picosecond Nd:YVO4 oscillator. Repetition frequencies exceeding 1MHz are obtained with pulse energies of more than 300nJ /1 microJ. Being compact and easy to operate light sources, these laser systems open up various scientific and industrial applications.

ABSTRACT

Multi-energy and chaotic pulse energy output from a continuously pumped regenerative amplifier is observed for dumping rates around the inverse upper state lifetime of the gain medium. The relevant regimes of operation are analyzed numerically and experimentally in a diode-pumped Yb:glass regenerative amplifier. The boundaries between stable and unstable pulsing are identified and stability criteria in dependence on the amplifier gate length and pump power are discussed.
