PROJECT TITLE :

Cryogenic Yb:YAG Laser Pumped by VBG-Stabilized Narrowband Laser Diode at 969 nm

ABSTRACT:

We have a tendency to present the laser performance of Yb:YAG at completely different cryogenic temperatures pumped by a volume Bragg grating (VBG)-stabilized narrowband fiber-coupled diode laser emitting at 968.7 nm for the first time to the best of our data. A most output power of half-dozen.54 W with a slope potency as high as sixty four.half dozen% is achieved at 140 K. The optimum temperature for 968.7 nm and 0.35 nm bandwidth VBG-stabilized pump source is found to be 140 K for Yb:YAG.
