Green output miniature Nd:BGO laser used in optical storage and image processing

摘要

Stable green output was obtained in the laser diode array pumped intracavity-doubled Nd:BGO (Nd-doped Bi$-4$/Ge$- 3$/O$-12$/) laser by using a birefringent filter formed by a Brewster plate and a birefringent KTP crystal. Compared with Nd:YAG, the Nd:BGO crystal has many unique advantages. The devices demonstrated in this paper are expected to find applications in optical storage and image processing.
