Nonlinear Crystals

  • Beta-Barium Borate (β-BaB2O4,BBO) or BBO crystal is an excellent non-linear crystal for frequency-conversion (SHG,THG, 4HG and 5HG) of Visible and Near IR laser light, OPO/OPG/OPA pumped by ultrafast pulses of wavelengths in the Near IR to UV, and sum-frequency mixing (SFM) into the Visible to the deep UV. BBO crystals is also used in the EO Q-switches for its high electro-optical coefficients. BBO is one of the few practical crystal for use below 500 nm in SHG and SFM. Hangzhou Shalom EO offers the custom BBO crystals upon customer's request, and there is also some types of standard BBO crystals in stock for your selection.
  • Potassium Titanyl Phosphate (KTiOPO3 or KTP) is an excellent optical crystals suitable for use in many optical systems. It has high nonlinear coefficient and stable physical property. Its most popular application is as a frequency doubler of 1064nm to generate 532nm laser.KTP's properties also make it superior for electro-optic modulation (EO components), optical parametric generation (OPO or OPA components). KTP crystals are widely used in commercial and military lasers including laboratory and medical systems, range-finders, lidar, and industrial systems.
  • Potassium Dideuterium Phosphate (DKDP or KD*P ) are among the most widely-used commercial NLO's crystals, characterized by good UV transmission, high damage threshold, and high birefringence, though their NLO coefficients are relatively low. They are usually used for doubling (SHG), tripling (THG) and quadrupling (FHG) of a Nd:YAG laser at the room temperature. In addition, they are also excellent electro-optic crystals with high electro-optic coefficients, makes it be widely used as electro-optical modulators, such as EO Q-switches, EO Pockels Cells, etc.
  • Lithium Tri-borate or LBO crystals (LiB3O5) is one of the most useful nonlinear optical material not just for its relatively large conversion coefficient - 3x that of KDP, but also for its excellent physical properties. LBO crystal has broad optical transparency range from 160 to 2600nm. LBO is widely used for SHG and THG of Nd:YAG, Nd:YLF, Nd:YVO4 and ultra-fast Ti:sapphire lasers. OPOs(Optical Parametric Oscillators) and OPAs(Optical Parametric Amplifier).
  • BIBO( BiB3O6) is a newly developed nonlinear Optical Crystal. It possesses large effective nonlinear coefficient, 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. The top-seeded solution growth (TSSG) technique is used for the growth of BIBO single crystals.
  • Potassium Titanyle Arsenate(KTiOAsO4), or KTA crystal, is an excellent nonlinear optical crystal for Optical Parametric Oscillation (OPO) application. It has better non-linear optical and electro-optical coefficients, significantly reduced absorption in the 2.0-5.0 µm region, broad angular and temperature bandwidth, low dielectric constants. And its low ionic conductivities   result in higher damage threshold compared with KTP .
  • RTP (Rubidium Titanyle Phosphate – RbTiOPO4) is an isomorph of KTP crystal which is used in nonlinear and electro optical applications. It has advantages of higher damage threshold(about 1.8 times of KTP), high resistivity, high repetition rate, no hygroscopic and no induce piezo-electric effect with electrical signals up to 60 kHz. Its transmission range is 350nm to 4500nm. Hangzhou Shalom Eo offers the custom RTP crystals upon customer's request
  • Lithium Iodate or LilO3 crystal is an uniaxial nonlinear crystal with high nonlinear optical coefficients and wide transparency range of 0.5μm to 5.0μm. It is used to frequency double the low and medium power Ti:Sapphire, Alexandrite, Cr:LiSrAlF6 and Cr:LiCaAlF6 lasers. It is also used for frequency doubling and tripling of Nd:YAG lasers and auto-correlators for measuring ultra-short pulse width. In some cases, it is used in the parametric oscillation to get continuous tunable laser at 0.9μm to 1.2μm. The LiIO3 crystals is highly hygroscopic, it is suggested to put in a dry environment. LiTaO3 is a low damaging threshold crystals, it is not suitable for high power laser applications.
