Abstract
We demonstrate a laser-diode-pumped gain-switched Er3+-doped ZrF4-BaF2-LaF3-AlF3-NaF (ZBLAN) fiber laser operating in a single transverse mode at 2.8 \( \mu \)m. The laser pulses produced offer high-pulse energies, with repetition rates ranging from 50 Hz to 10 kHz and a slope efficiency of approximately 14.3% with respect to the launched pump power. The average power at the 50 Hz repetition rate is 1.33 W, giving a maximum total output pulse energy of 26.6 mJ per pump pulse. The fiber laser operates in a single mode, with beam quality factor M2 less than 1.2.
