Method and Apparatus for Narrowing the Spectral Emission from High-Power Laser Diodes
Methods and apparatus for spectral narrowing and wavelength stabilization of broad-area lasers, such as an apparatus including a broad-area laser source configured to emit light along an emission axis in an emission pattern extending along the emission axis, and a single-mode fiber Bragg grating, such as a single-mode core incorporating a fiber Bragg...

Method and Apparatus for Efficient Lasing of Lambda-Type Three-Level Laser Systems
Laser signal intensity is resonantly enhanced within a laser cavity to be greater than a pump intensity. This enables the suppression of excited-state absorption and is applicable to terbium-doped fiber lasers, lambda-type materials, or other materials used in lasers. In other embodiments, ESA is suppressed by de-populating the higher excited state...
