Abstract
An efficient Cesium vapor laser pumped with a continuous wave narrowband Laser Diode Array (LDA) has been demonstrated. To obtain a high lasing efficiency, it is necessary to narrow the linewidth of the pumping LDA to match the Cs atom absorption line. An external cavity with holographic grating was used to narrow the linewidth of a commercially available LDA to a value of 11 GHz that matches the Cs vapor absorption line broadened by a buffer gas at atmospheric pressure. The developed pump source was used for pumping a Cs vapor laser, which operated at 894 nm. Preliminary experiments yielded 400 mW output power and about 20% slope efficiency. The laser efficiency can be significantly increased by optimizing the cell and cavity design and matching the pump beam to the cavity mode size.
