E-O Crystals ------>> KTP

KTP has promising E-O and dielectric properties comparable to those of LiNbO 3; , which makes it extremely useful to various E-O devices. The following table gives the comparison of KTP and thos commonly used E-O modulator materials:

When these properties are combined with high damage threshold, low optical loss at high average power, wide optical bandwidth, thermal and mechanical stability, KTP crystals are expected to replace LiNbO 3; crystals as E-O modulators, especially for mode-locking diode laser pumped Nd:YAG and Nd:YLF lasers as well as Ti:Sapphire and Cr:LiSrAlF 6 lasers.
