Laser operation near 1.06 μm by a diode-pumped Nd:(LuxGd1-x)3Ga5O12 (Nd:LGGG) disordered crystal has been investigated. Cw oscillation, with a slope efficiency as high as 61% and 230 mW output power, was achieved with 400 mW absorbed power from a 1-W laser diode. Stable passive mode-locking with single- or multi-banded spectrum was obtained with a semiconductor saturable absorber mirror (SAM) and a single-prism, dispersion-compensated cavity. Fourier-limited pulses with duration ≈ 3 - 9 ps and output power ≈ 40 mW were generated at three well-defined laser transitions in the range 1062-1067 nm.

Abstract
Laser operation near 1.06 μm by a diode-pumped Nd:(LuxGd1-x)3Ga5O12 (Nd:LGGG) disordered crystal has been investigated. Cw oscillation, with a slope efficiency as high as 61% and 230 mW output power, was achieved with 400 mW absorbed power from a 1-W laser diode. Stable passive mode-locking with single- or multi-banded spectrum was obtained with a semiconductor saturable absorber mirror (SAM) and a single-prism, dispersion-compensated cavity. Fourier-limited pulses with duration ≈ 3 - 9 ps and output power ≈ 40 mW were generated at three well-defined laser transitions in the range 1062-1067 nm.File in questo prodotto:
