We apply the technique of nonlinear mirror (NLM) mode-locking to a pulsed diode-pumped, actively modelocked Nd:YAG laser. Either effective pulse compression or pulse amplitude control regimes are achieved, depending on the NLM configuration. Operating the NLM as a fast saturable absorber, 34 ps-long pulses are emitted in a 450 ns long train, with 0.5 mJ energy, at a maximum repetition rate of 100 Hz. Alternatively, in the pulse amplitude control regime, 100 ms-long flat trains of active mode-locking pulses are generated. In both cases, amplitude fluctuations lower than 2% (rms) were routinely obtained.

Abstract
We apply the technique of nonlinear mirror (NLM) mode-locking to a pulsed diode-pumped, actively modelocked Nd:YAG laser. Either effective pulse compression or pulse amplitude control regimes are achieved, depending on the NLM configuration. Operating the NLM as a fast saturable absorber, 34 ps-long pulses are emitted in a 450 ns long train, with 0.5 mJ energy, at a maximum repetition rate of 100 Hz. Alternatively, in the pulse amplitude control regime, 100 ms-long flat trains of active mode-locking pulses are generated. In both cases, amplitude fluctuations lower than 2% (rms) were routinely obtained.File in questo prodotto:
