Abstract

Continuous-wave and Q-switched lasing from a Tm3+/Ho 3+ codoped tellurite fiber is reported. An Yb3+/Er 3+-doped silica fiber laser operating at 1.6 μm was used as an in-band pump source, exciting the Tm3+ ions into the 3F4 level. Energy is then nonradiatively transferred to the upper laser level, the 5I7 state of Ho3+. The laser transition is from the 5I7 level to the 5I8 level, 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. © 2008 Optical Society of America.
