Abstract

It is believable that a diode pumped alkali laser (DPAL) will generate a continue-wave (CW) high-powered output in the near future. In this paper, we report the first experimental demonstration of modulating a laser-pumped rubidium-cesium vapor laser system with two wavelengths. Being different from the conventional dual-wavelength solid-state lasers in which stimulated emissions with two wavelengths often interfere with each other, the rubidium-cesium vapor laser with two wavelengths, i.e. 794.736 nm for rubidium and 894.335 nm for cesium, has a prominent advantage of employing different alkali metal vapors as laser media in the same oscillator without any disturbance in the lasing processes for dual wavelengths. In the study, we also modulated one pump source and kept the other pump source unchanged in time domain. The experimental results reveal that such a rubidium-cesium vapor laser may provide a new light source for the applications in the fields of laser ranging, laser radar, and laser surface depiction.
