Abstract

We demonstrate a Q-switched, cladding-pumped, Nd:Al-doped silica depressed clad hollow optical fiber (DCHOF) laser, which generated up to 133 μ J of pulse energy at a repetition rate of 5 kHz and 0.9 W of average output power at a high repetition rate ( > 20 kHz ) in a diffraction-limited beam ( M 2 = 1.08 ) at 927 nm . The laser was tunable from 919 to 935 nm . This result shows the potential of the DCHOF structure for the suppression of unwanted long-wavelength radiation in large-area cores suitable for high-power Q-switched laser operation.
