(Color online) Schematic diagram of a broad-area LDA coupled with VBG. A beam-rotated lens array and two cylindrical lenses FAC and SAC were used to shape the LDA beam.
(Color online) Measured central wavelength and output pulse energy vs drive current of the VBG-coupled LDA used in the experiment. At left upside of the illustration, the spectrum is also shown for the VBG-coupled LDA.
(Color online) Experimental setup of the pump optical system and the atomic cesium vapor laser resonator. The -polarized pump energy passes the vapor cell while forming an -polarized cesium laser radiation through an -typed oscillation cavity.
(Color online) Pulse shape of the cesium vapor laser. The relaxation oscillation can be observed through many cyclical subpeaks appearing in the pulse characteristics.
(Color online) Output pulse energy of cesium vapor laser as a function of incident pump pulse energy from the VBG-coupled LDA with the slope efficiency of .
