Temperature insensitive SHG at 0.5321 mu m in KTP

KTP has been found to have the special phase-matching loci where the temperature-induced phase mismatch becomes zero for type-1 and type-2 SHG of the Nd:YAG laser frequency at 1.0642 mu m. This was demonstrated for type-1 phase matching. In addition, the temperature derivatives of the refractive indexes and the absolute value of d/sub 33/ are reported.<
