  • Title: SCPEM-Q-switching of a fiber-rod-laser.
    Author: Petkovšek R, Saby J, Salin F, Schumi T, Bammer F.
    Journal: Opt Express; 2012 Mar 26; 20(7):7415-21. PubMed ID: 22453421.
    Abstract:
    We demonstrate high-frequency Q-switching of a fiber rod laser with a Single-Crystal Photo-Elastic Modulator (SCPEM) made of a LiTaO₃₋ crystal. This type of photo-elastic modulator can be driven simultaneously with two different eigenmodes to achieve a shorter rise time, which is essential for high-power operation. When operated in the laser cavity, a pulse repetition frequency of 183.6 kHz with an average power of 47 W, a pulse duration of 26 ns, and a peak power of 10.5 kW was achieved.
