Abstract

Continuous-wave and Q-switched lasing from a Tm 3 + Ho 3 + codoped tellurite fiber is reported. An Yb 3 + Er 3 + -doped silica fiber laser operating at 1.6 μ m was used as an in-band pump source, exciting the Tm 3 + ions into the F 4 3 level. Energy is then nonradiatively transferred to the upper laser level, the I 7 5 state of Ho 3 + . The laser transition is from the I 7 5 level to the I 8 5 level, and the resulting emission is at 2.1 μ m . 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 μ J energy and 160 ns duration at a repetition rate of 19.4 kHz .
