摘要：

A gain-switched laser transition, of a two-laser-transition cascade laser, that is driven by the adjacent laser transition which is Q-switched is demonstrated using a Ho3+-doped fluoride fiber laser. Q-switching the I-5(6) -> I-5(7) transition at 3.002 mu m produces stable gain-switched pulses from the I-5(7) -> I-5(8) transition at 2.074 mu m; however, Q-switching the I-5(7) -> I-5(8) transition produced multiple gain switched pulses from the I-5(6) -> I-5(7) transition. The gain-switched pulses were measured to be of a similar duration to the Q-switched pulses suggesting that much shorter pulses of closer duration could be generated at pump power higher levels.
