Tj. Carrig et Cr. Pollock, PERFORMANCE OF A CONTINUOUS-WAVE FORSTERITE LASER WITH KRYPTON ION, TI-SAPPHIRE, AND ND-YAG PUMP LASERS, IEEE journal of quantum electronics, 29(11), 1993, pp. 2835-2844
We characterize continuous-wave operation of a chromium-doped forsteri
te (Cr4+:Mg2SiO4) laser using krypton ion, Ti:sapphire, and-Nd:YAG las
ers as pump sources, Measurements were made pumping at 647 nm and 676
nm with the krypton ion laser, between 690 and 1010 nm with the Ti:sap
phire laser and at 1.06 mu m with the Nd:YAG laser. Threshold pump pow
ers and slope efficiencies are compared for output coupler transmissio
ns varying between I and 15.5%. Room temperature operation was only ac
hieved using the Nd:YAG pump laser. Forsterite laser output power as a
function of both temperature and pumping wavelength is discussed.
