| description | TiB<sub>2</sub> nanoparticles with a bandgap of 0 eV were prepared, and the corresponding nonlinear optical response at 2.85 μm was investigated. Employing a TiB<sub>2</sub> as a saturable absorber, a 2.85 μm pulsed Er:Lu<sub>2</sub>O<sub>3</sub> crystal laser with an average output power of 1.2 W was achieved under a maximum pump power of 9.51 W. Laser pulses with durations of ~203 ns were delivered at a repetition rate of 154 kHz, which corresponds to a pulse energy of ~7.8 µJ and a peak power of 39.3 W. As far as we know, the result represents the highest average output power from all Q-switched Er:Lu<sub>2</sub>O<sub>3</sub> crystal lasers. |
