NLO Crystals


KTP crystal

KTP(KTiOPO4 ) is an efficient nonlinear optical crystal in the visible to infrared spectral region with relatively low cost. It has large nonlinear coefficient. The effective nonlinear optical coefficient of KTP deff at 1064nm is more than 1.5 times that of BBO. It's damage threshold is near 1 GW/cm2 for 1 Hz 10 ns pulses at 1064nm.




GTR-KTP crystal

GTR-KTP crystals have gray track resistance sufficiently greater than typical flux grown KTP. This is possible due to advances in the controlled growth of KTP crystals, using proprietary modified fluxes and heat treatment. These GTR-KTP crystals are suitable for high power density applications, where regular flux-grown KTP crystals would suffer from gray track damage.




BBO crystal


BBO (BaB2O4) is an excellent non-linear crystal for frequency-doubling (SHG) of Visible and Near IR laser light, OPO/OPG/OPA pumped by ultrafast pulses flux-grown BBO of high optical homogeneity produced under a strict regime of quality control.





BIBO crystal


BIBO ( BiB3O6) is a newly developed nonlinear Optical Crystal. It possesses large effective nonlinear coeffcient, high damage threshold and inertness with respect to moisture. Its nonlinear coefficient is 3.5-4 times higher than that of LBO,1.5-2 times higher than that of BBO. It is a promising doubling crystal to produce blue laser.




LBO crystal

LBO(LiB3O5)  is a non-linear optics crystal. It has a wide transparency range, moderately high nonlinear coupling, high damage threshold and desirable chemical and mechanical properties. This crystal is often used for second harmonic generation of Nd:YAG lasers. LBO can be both critically and non-critically phase-matched. In the latter case the crystal has to be heated or cooled depending on the wavelength.
