1150-nm Yb-Doped Fiber Laser Pumped Directly by Laser-Diode With an Output Power of 52 W

摘要

A high power, diode pumped, all-fiber Yb-doped fiber laser at 1150-nm wavelength by using conventional double clad fiber with output power of 52.6 W and slope efficiency up to 60% is realized. To the best of our knowledge, it is the highest power at this wavelength.
