ABSTRACT
We obtained for the first time efficient room-temperature cw lasing at 2.086 μm in Cr,Tm,Ho:YScAl-garnet and Cr,Tm,Ho:YScGa-garnet crystals. Double cross pumping via Cr3+ and Tm3+ with a krypton pump laser yields threshold pump powers of 25 mW and slope efficiencies up to 13%. Broad band pumping can also be expected.
