Wavelength Stabilization Technique for High-power Diode Lasers

Background High-power diode lasers (HDL’s) are used for optical pumping and material processing due to their wavelength selectability and high electrical-to-optical efficiency. However, owing to their spectrally and spatially erratic emission, 9xx-band broad area lasers have spectral widths from 2-6 nm at peak operating power and spectra that...

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...
