摘要: Extended quasi-steady-state pulse train is developed through the all-solid-state combination of passive negative feedback in a GaAs platelet and positive cascaded χ(2) polarization switching. With an actively mode-locked flash-lamp-pumped Nd3+:Y3Al5O12 laser, stationary trains lasting for 1μs with pulses duration 11.6ps energy 6.5μJ are obtained. The total output amounts 1.73mJ evolution demonstrates that semiconductor two photon absorption able to realize compression from 43.9to11.6ps.
