13 March 2008 A diode-pumped Rb laser at 398 nm
Author Affiliations +
The CW diode-pumped alkali laser (DPAL) based on the rubidium resonance transition at 794.8 nm has been investigated. The pump sources for these experiments are commercially available 780 nm fiber-coupled diode modules, incorporating volume holographic gratings for wavelength control. Operating characteristics, pump architecture, power scaling and lifetime limitations have been studied. To date, lasers pumped by single 20 W diode bars have produced over 1 W output at 794.8 nm and 100 mW at the 397.4 nm harmonic. Lasers pumped by two 40 W diodes generate almost 8 W at 794.8 nm.
