Optical and laser properties of (F(2)(+))(H) centers in sulfur-doped NaCl.
We report the production and main optical and laser properties of (F(2)(+))(H) color centers in sulfur-doped NaCl crystals. Using a 1.06-microm 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 microm. Output power levels are as much as ~800 mW near 1.6 microm; mode-locked pulse durations are typically 4-7 ps.
