Abstract

Continuous-wave and Q-switched lasing from a Tm3+/Ho3+codoped tellurite fiber is reported. An Yb3+/Er3+-doped silica fiber laser operating at 1.6 μm was used as an in-band pump source, exciting the Tm3+ions into the3F4level. Energy is then nonradiatively transferred to the upper laser level, the5I7state of Ho3+. The laser transition is from the5I7level to the5I8level, and the resulting emission is at 2.1 μm. For continuous wave operation, the slope efficiency was 62% and the threshold 0.1 W; the maximum output demonstrated was 0.16 W. Mechanical Q switching resulted in a pulse of 0.65 μJ energy and 160 ns duration at a repetition rate of 19.4 kHz.
