摘要:

We obtained for the first time efficient room‐temperature cw lasing at 2.086 &mgr;m 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.
