Abstract :
The only Yb-doped crystal lasers at 985 nm reported in this paper are a long pulse pumping quasicw Yb:S-FAP laser and a Ti:sapphire-pumped cw Yb:C4SFAP with a low slope efficiency of 5%. An efficient cw three-level laser operation at 985 nm with an Yb:doped bulk crystal is reported. The evaluation of the pump intensity necessary to reach transparency led use of Yb:S-FAP crystal among several host materials.
