Abstract

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 ⁵|₆ ? ⁵|₇ transition at 3.002 µm produces stable gain-switched pulses from the ⁵|₇ ? ⁵|₈ transition at 2.074 µm; however, Q-switching the ⁵|₇ ? ⁵|₈ transition produced multiple gain switched pulses from the ⁵|₆ ? ^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.
