Implication

Experimental study demonstrates a 12 W actively Q-switched fiber laser at 2.8 μm, highlighting a major power advance for mid-infrared pulsed laser systems.

Key Points

To achieve high-average-power pulsed operation from an actively Q-switched mid-infrared fiber laser in the 3 μm wavelength band.
Constructed a diode-pumped fiber laser oscillator using a 35 μm core erbium-doped ZBLAN fiber.
Incorporated an acousto-optic modulator into the cavity to enable active Q-switching.
Generated an average output power exceeding 12 W at 2.8 μm, establishing the first 10 W-class pulsed fiber laser in the 3 μm band.
Achieved pulse energy up to 100 μJ, pulse duration down to 90 ns, and peak power of 0.9 kW at a 120 kHz repetition rate.
