Broadly tunable cw laser emission is reported in Tm:YAG and Tm:YSGG at room temperature with Ti:sapphire laser pumping. The Tm(3+)(3)F(4) ? (3)H(6) transition is tuned continuously over the ranges 1.87-2.16 microm in YAG and 1.85-2.14 microm in YSGG. Smooth tuning results from overlapping transitions between phonon-broadened crystal field Stark levels.
据报道，在室温下用钛宝石激光器泵浦的掺铥钇铝石榴石（Tm:YAG）和掺铥钇钪镓石榴石（Tm:YSGG）中实现了宽可调谐连续波激光发射。在YAG中，Tm(3+)的(3)F(4)→(3)H(6)跃迁在1.87 - 2.16微米范围内连续调谐，在YSGG中则在1.85 - 2.14微米范围内连续调谐。平滑调谐源于声子展宽的晶体场斯塔克能级之间的跃迁重叠。
