Abstract

We characterize continuous-wave operation of a chromium-doped forsterite (Cr⁴⁺:Mg₂SiO₄) laser using krypton ion, Ti:sapphire, and Nd:YAG lasers 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:sapphire laser and at 1.06 pm with the Nd:YAG laser. Threshold pump powers and slope efficiencies are compared for output coupler transmissions varying between 1 and 15.5%. Laser output power as a function of temperature is also discussed.
