Abstract :
Summary form only given. We have proposed an alternative possibility that spectrally narrowed gain-switched semiconductor laser pulses can be used as fundamental light (FL) to generate quasi-cw UV light and have shown experimentally the improvement of the UV second-harmonic generation (SHG) efficiency. We report successful compression of such pulses from a 690-nm AlGaInP semiconductor laser by a Gires-Tournois (GT) interferometer and the SHG efficiency improvement achieved with it. The method to make the pulses spectrally narrowed is the same as before. The GT interferometer was placed between the laser and the SHG crystal.
