Laser Crystals and Components

Nonlinear Crystals

A Nonlinear Crystal or an  NLO Crystal is an optical crystal that exhibits a strong nonlinear dielectric response function to optical radiation. Nonlinear crystals are important components in the fields of photonics and lasers. One of the major applications of NLO crystals is Nonlinear Optical Conversion of Frequencies, where laser wavelengths that are inaccessible (e.g. 2-7 micro wavelengths) without deliberate interventions are generated by altering the frequencies (hence the wavelength) of the output light. And some of them could also be utilized as EO/AO Modulation crystals.

Hangzhou Shalom EO offers various off-the-shelf and custom nonlinear crystals with versatile functions, including: Beta Barium Borate (Beta BBO) Crystals, Ultra-thin Beta BBO for Femtoline Lasers, Potassium Dideuterium Phosphate (KDP/DKDP) Crystals, Lithium Triborate (LBO) Crystals, Potassium Titanyl Phosphate (KTP/HGTR KTP) Crystals, Potassium Titanyle Arsenate (KTA) Crystals, Bismuth Borate (BIBO) Crystals, Lithium Iodate (LiIO3) Crystals, LiNbO3 (Lithium Niobate)/MgO:LiNbO3 Crystals, RTP Crystals, and ZnGeP2 (ZGP) Crystals. The nonlinear crystals feature laser-grade polished with high geometric precision/flexible coating options, and a wide transmission range covering Ultra Violet to Infrared wavelength region. The crystals feature large nonlinearities, high damage threshold, and large-dimension capabilities. Our crystals are compliant with various phase-matching techniques (e,g critical/non-critical phase matching), and capable of coping with a broad assortment of Conversion of Frequencies purposes, encompassing: Second Harmonic Generation/Doubling Frequencies(SHG), Third Harmonic Generation (THG), Fourth Harmonic Generation (4HG), and Fifth Harmonic Generation (5HG), SFG/DFG, Optical Parametric Oscillation (OPO), and Optical Parametric Amplification (OPA) for laser output generation. In addition, the crystals are also requisite for EO and AO Modulations, Spontaneous Parametric Down Conversion (SPDC).
