5-µm Lasing on Tb3+ Ions in a Chalcogenide Fiber Pumped by a 2.8-µm Er:ZBLAN Laser
Mid-IR lasing of a Tb3+-doped chalcogenide fiber has been demonstrated. Pumping was performed by a CW Er:ZBLAN laser, emitting at a wavelength of 2.795 µm. Fiber length optimization has made it possible to obtain output power up to 2 mW in the wavelength range of 5.2–5.3 µm at 1.8% slope efficiency and room temperature.
