Zy. Xu et al., MULTIWAVELENGTH OPTICAL PARAMETRIC AMPLIFICATION WITH ANGLE-TUNED LITHIUM TRIBORATE, Journal of the Optical Society of America. B, Optical physics, 12(11), 1995, pp. 2222-2228
The retracing behavior of the phase matching in optical parametric pro
cesses with angle-tuned LiB3O5 crystals has been investigated. The sim
ultaneous generation of two pairs of parametric beams and a novel mult
iwavelength interaction phenomenon have been observed and analyzed. Th
e design and performance of a picosecond multiwavelength optical param
etric amplifier with three angle-tuned lithium triborate crystals is d
escribed. As much as 2.34 mJ/pulse of output, corresponding to a conve
rsion efficiency of 26%, has been obtained. (C) 1995 Optical Society o
