Simultaneous dual-wavelength oscillation at 1357 nm and 1444 nm in a Kr-flashlamp pumped Nd:YAG laser

A Nd:YAG laser pumped by a Kr-flashlamp with simultaneous dual-wavelength operation at 1357 nm (F-4(3/2) -> I-4(13/2)(R-1 -> X-4)) and 1444 nm (F-4(3/2) -> I-4(13/2)(R-1 -> X-7)) is demonstrated and its characteristics was analyzed. The output energy of 82 m] at 1357 nm and 138 mJ at 1444 nm were achieved simultaneously with the maximum electrical input energy of 44J. Stability of the output energy in the dual-wavelength operation was 1.41% at the maximum input energy of 44J. However, the stabilities at each wavelength in the dual-wavelength operation showed much lower stability. (C) 2008 Elsevier B.V. All rights reserved.
