Characteristics of Nd:YGG Laser Operating at 4F3/2-4I9/2

The laser properties of the Nd:YGG crystal are investigated. The absorption spectrum from 500 to 900nm and emission spectrum from 850 to 1400nm of Nd:YGG are measured. As much as 1.35W output power of fundamental laseroperating at 935 and 938nm with a slope efficiency of 15.7% and 105mW output power of frequency doubled blue laser are successfully obtained.
