Abstract
A Cr3+:LiSAF laser oscillator self-injection locked by an externally coupled fiber grating was constructed. Single-mode operation in a Cr3+:LiSAF laser was obtained by use of a 67%-reflectivity fiber grating that was fabricated with a holographic technique in which a narrow-band KrF UV laser exposure was used. This configuration permits the use of a fiber grating with optimum reflectivity for efficient single-mode operation.
