M. Ostermeyer et R. Menzel, 34-WATT FLASH-LAMP-PUMPED SINGLE-ROD ND-YAG LASER WITH 1.2-ASTERISK-DL BEAM QUALITY VIA SPECIAL RESONATOR DESIGN, Applied physics. B, Lasers and optics, 65(4-5), 1997, pp. 669-671
With a special resonator design guaranteeing fundamental-mode operatio
n a single-rod Nd:YAG (4 mm x 79 mm) oscillator was realized with an a
verage output power of up to 34 W TEMinfinity. The total efficiency wa
s greater than 0.9% and the beam quality was better than 1.2DL for al
l realized output powers between 7 and 34 W. The pulse-to-pulse fluctu
ations of the laser running at a repetition rate of 50 Hz were below 3
.2%.
