Quasi-continuously pumped acousto-optically mode-locked highly-doped Nd:YAG laser in bounce geometry

Popis výsledku v původním jazyce

In this paper we demonstrate efficient operation of the actively mode-locked Nd:YAG laser operating at the wavelength of 1,06 mm in bounce geometry under quasi-continuous diode pumping. The laser output pulse train consisted of ~50 pulses (at FWHM) withthe total energy of 90 mJ, energetic stability better than 2 %, and Gaussian beam profile was generated directly from the oscillator. The mean pulse duration was measured to be 160 ps at FWHM. This regime was compared with actively-passively mode lockedoperation using a semiconductor saturable absorber mirror as a passive mode-locking element. Stable generation of single Q-switched and mode-locked train was achieved. The number of pulses decreased to ~10 pulses (at FWHM) and whole train energy increased to 160 mJ. Single pulse duration was shorter than our detection system limit of ~76 ps. The output pulse train generation stability and timing jitter decrease down to 260 ns show the advantage of using the active stabilization in quasi-
