Nd:YVO4 Crystals
Nd:YVO4 is the most efficient laser host crystal for diode pumping among the current commercial laser crystals, especially, for low to middle power density. This is mainly for its absorption and emission features surpassing Nd:YAG. Pumped by laser diodes, Nd:YVO4 crystal has been incorporated with high NLO coefficient crystals ( LBO, BBO, or KTP) to frequency-shift the output from the near infrared to green, blue, or even UV.

LiNbO3 Crystals
LiNbO3 Crystal has unique electro-optical, piezoelectric, photoelastic and nonlinear optical properties. They are strongly birefringent. They are used in laserfrequency doubling, nonlinear optics, Pockels cells, optical parametric oscillators, Q-switching devices for lasers, other acousto-opticdevices, optical switches for gigahertz frequencies, etc. It is an excellent material for manufacture of optical waveguides, etc.

LGS Crystals
La3Ga5SiO14 crystal (LGS crystal) is an optical nonlinear material with high damage threshold, high electro-optical coefficient and excellent electro-optical performance. LGS crystal belongs to trigonal system structure, smaller thermal expansion coefficient, thermal expansion anisotropy of crystal is weak, the temperature of the high temperature stability is good (better than SiO2), with two independent electro – optical coefficients are as good as those of BBO Crystals.
