Shalom EO offers a vast selection of nonlinear crystals, including BBO, CLBO crystals, KDP and KD^*P, LBO, KTP, HGTR KTP, KTA, BIBO, LiIO₃, LiNbO₃, MgO:LiNbO₃, RTP, ultra-thin BBO, LBO crystals and infrared nonlinear crystals ZnGeP₂ (ZGP). KGW crystals for stimulated Raman scattering are also available.

Our nonlinear crystals are excellent for applications ranging from frequency conversion to short-pulse generation. The NLO crystals offer reliable performance for harmonic generation (SHG, THG, 4HG, 5HG), sum and difference frequency generation (SFG, DFG), for optical parametric oscillators (OPOs) and optical parametric amplifiers (OPAs). Off-the-shelf and customized crystals are optional for our customers. Miscellaneous coating options including uncoated, AR, HR, HT, PR coatings, and custom coatings can be tailored. All the crystals will undergo rigorous inspection before dispatch.

Recent days, Shalom EO has launched CLBO crystals. The ClBO processed and polished in low humidity workshop are ideal for FHOG and FIHG for Nd: lasers, SHG and THG for Ti:sapphire and Alexandrite lasers, and micro-lithography.

In addition, electro-optic (EO) crystals and acousto-optic (AO) crystals are also available.

Nonlinear crystals of either β-barium borate (BBO) or lithium triborate (LBO) are used for frequency conversion of laser sources. BBO crystals feature thicknesses from 0.2 mm to 0.5 mm to minimize group velocity mismatch and are ideal for frequency doubling or tripling of Ti:sapphire and Yb:doped laser pulses. The critical and noncritical phase matching LBO crystals are ideal for second or third harmonic generation of Nd:YAG and Yb:doped lasers.

Nonlinear crystals with 20-10 surface quality and λ/10 (LBO) or λ/8 (BBO) surface flatness provide the broad transparency range and large nonlinear coefficient needed for the harmonic generation of fundamental laser frequencies. Each crystal features a protective anti-reflection (AR) coating that minimizes reflection and limits fogging from ambient conditions.

Non-linear Optical (NLO) crystals provide an enormously flexible solution for generating new wavelengths from existing, off-the-shelf laser sources. The optical wavelength spectrum is utilized by a large and continually expanding variety of applications, from manufacturing of medical lasers, quantum networking & computing through to environmental sensing as well as many others.

With its high non-linear coefficient, ability to be periodically poled and broad optical transmission, MgO:PPLN becomes a highly flexible solution for the generation wavelengths from the blue (400 nm) through the mid-IR and beyond (THz).
