Continuous wave laser emission at 2.1 microm from a Yb(3+)/Tm(3+)/Ho(3+) triply-doped tellurite fibre laser is reported. The fibre was pumped at 1.1 microm by a Yb(3+)-doped double-clad silica fibre laser. For a 17 cm fibre length and 99%???60% reflectance cavity, the threshold was 15 mW and the slope efficiency was 25%. A maximum output of 60 mW was observed for a launched pump power of 270 mW, corresponding to 22% optical-to-optical efficiency.
据报道，一种掺镱（Yb(3+)）/铥（Tm(3+)）/钬（Ho(3+)）的碲酸盐光纤激光器能在2.1微米波长处产生连续波激光发射。该光纤由一个掺镱（Yb(3+)）的双包层石英光纤激光器在1.1微米波长处泵浦。对于长度为17厘米、反射率为99%???60%的谐振腔，阈值为15毫瓦，斜率效率为25%。当泵浦功率为270毫瓦时，观察到最大输出功率为60毫瓦，对应光光效率为22%。
