We report a cesium vapor laser with fundamental mode output and a wavelength of 894 nm.The laser is pumped by a laser diode array with an exteal cavity of a holographic grating by using Littrows structure.A slope efficiency of 22.4 % is obtained by using a pumping source with a linewidth of 0.26 nm and 80 kPa methane as the buffer gas.The threshold pumping power is 1.56 W.
