Abstract

Abstract: Based on the pulsed laser deposition (PLD) method, we first fabricated a mid-infrared Fe 2+ :ZnSe film saturable absorber (SA). By employing the PLD Fe 2+ :ZnSe film SA, we have demonstrated a passively Q-switched double-clad Er 3+ -doped ZBLAN fiber laser operating at a wavelength of 2.78 μ m. Stable Q-switched pulses with pulse energy of 7.98 μ J and pulse duration of 0.742 μ s, corresponding to a peak power of 10.76 W, were obtained at a repetition rate of 102.94 kHz. The maximum average output power is 822 mW. Our results demostrate that the PLD-Fe 2+ :ZnSe film SA is promising for high power pulse generation in compact mid-infrared fiber lasers.
