Abstract
We report highly efficient cascade tripling of 1.32 micrometers Nd:YAG laser emission using combination of LiIO3 and KTP crystals. The generation of 0.44 micrometers radiation in KTP has been shown to occur at the purely noncritical phase-matching condition at slightly elevated temperature. Conversion efficiency of third harmonic generation in relation to second harmonic energy was approximately 60% in 4 mm long KTP crystal. The temperature and angular characteristics of conversion are presented.
