Check List for Nonlinear Crystal Materials

Click here to see a check list before buying such products!
  • Are you sure that you are using the best suited nonlinear crystal material and dimensions for your application? If not, you may want to consult an expert.
  • Check the required crystal dimensions.
  • Will the crystal quality be sufficiently high? Possible aspects of relevance: homogeneous refractive index, parasitic absorption.
  • Is the surface quality high enough? For example scratch/dig 10–5 and λ/20 for demanding applications?
  • What is the proper crystal orientation? How can it be recognized if it is not obvious from the geometry?
  • Do you need anti-reflection coatings on the end faces?

In case that you need additional advice, consultancy from RP Photonics may be the solution.

nonlinear crystal materials

Periodically poled lithium niobate: magnesium-doped PPLN is ideal for innovative laser applications due to its high effective nonlinear coefficient; allowing for high efficiency frequency conversion across multiple different mechanisms.

Covesion is a world leader in the design and manufacture of periodically poled lithium niobate for non-linear frequency conversion. MgO:PPLN crystals are available for high efficiency SHG, DFG, SFG and OPO interactions. Wavelength generation coverage runs from visible to mid-IR.

Periodic poling allows for quasi phase matching, which maintains phase relation of the photons throughout the crystal where they would otherwise fall out of phase. This engineered effect leads to a much higher conversion efficiency than would be found in the regular crystal.

Readily available stock crystals and waveguides can be provided on short timescales to rapidly meet your application needs, providing the capability to generate laser light in a wide range of wavelengths.

nonlinear crystal materials

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.
