Abstract

We report what we believe to be the first demonstration of a multimode-diode-pumped gas laser: Rb vapor operating on the 795 nm D1 resonance transition. Peak output of 1W was obtained using a volume-Bragg-grating stabilized pump diode array. The laser’s output radiance exceeded the pump radiance by a factor greater than 2000. Power scaling (by pumping with larger diode arrays) is therefore possible.

Calculated points were obtained with the model of Ref. [4]. (c) Peak output power versus cell temperature, using the 50% output coupler.
