Paper Abstract

Visible laser diodes are used to pump a co-doped Cr,Nd:Gd3Sc2Ga3O12 (Cr,Nd:GSGG) laser rod, demonstrating efficient operation at 1.06 (mu) . Using a 10 cm ROC HR output coupler, the absorbed power required to reach threshold was 938 (mu) W. The round trip losses in the 5 mm long rod were measured to be 4 X 10-3. The best slope efficiency was 42.1%, obtained with a 97% R output coupler. The photon slope efficiency was 66.8%.
