High Power Tm-doped All-Fiber Amplifier at 2130 nm

Not Accessible

Your library or personal account may give you access

Abstract

A diode pumped (793nm), long-wavelength thulium-doped all-fiber amplifier was demonstrated. Laser gain competition was used to suppress parasitic lasing and an output power of 80 W was generated at 2130nm with 50% optical efficiency.
