We report the production and main optical and laser properties of (F2+)H color centers in sulfur-doped NaCl crystals. Using a 1.06-µm Nd:YAG laser as the pump source, we realize continuous-wave and synchronously mode-locked laser operation. The laser is tunable over a remarkably large wavelength range of 1.43–2.0 µm. Output power levels are as much as ~800 mW near 1.6 µm; mode-locked pulse durations are typically 4–7 ps.
