KTP crystal has promising E-O
and dielectric properties comparable to those of LiNbO3, which makes it
extremely useful to various E-O devices. The following table compares KTP
with other commonly used E-O modulator materials:

Combined these properties with high damage threshold, low optical loss at high average power, wide optical
bandwidth, thermal and mechanical stability, KTP are expected to
replace LiNbO3 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:LiSrAlF6
lasers, KTP is the the crystal of choice. KTP was successfully used to mode lock a diode laser pumped
Nd:YLF laser at 270 MHz with pulse width of 15 ps and spectral bandwidth of 73
GHz.
