RESUMEN
In this Letter, we report a titanium nitride (Ti4N3Tx) passive Q-switched Er:Lu2O3 laser. The homemade two-dimensional Ti4N3Tx saturable absorber shows excellent passive Q-switching performance around a 2.85 µm wavelength region. Under the absorbed pump power of 7.4 W, the passive Q-switching laser yields a maximum output power of 0.778 W at a pulse repetition rate of 113.7 kHz, corresponding to a single pulse energy of 6.84 µJ and peak power of 24.57 W.
