Buying Periodically Poled Nonlinear Crystals

Top-level product categories: materials, various devices

More general product categories: nonlinear crystal materials

Periodically poled nonlinear crystals enable quasi-phase-matched nonlinear processes where standard phase matching is not possible. The appropriate poling period allows quasi-phase-matching for various nonlinear processes.

Making Good Purchase Decisions

RP Photonics helps you to not only to find all relevant suppliers, but also to make good purchasing decisions.

NEW: Structured Decision Process

We recommend that you apply best practice by using the following structured process: Go through the following expandable sections, complete the form and finally come to a purchase decision. You can then print that to a PDF for documenting the process.

(Various further improvements of this feature will come soon.)

1. Learn about the technology

It is important to sufficiently understand the technology before buying.

encyclopedia article

With its comprehensive resources, RP Photonics helps you to well prepare purchase decisions:

2. Define your requirements

It is important to fully understand and define your requirements before you buy.

We recommend that for your preparation and for inquiries to suppliers, you draw up a list of clear specifications according to your specific needs:

To help you, we have already listed some aspects we recommend you consider when buying periodically poled nonlinear crystals. Of course, there may be other aspects that are relevant to your specific case.

Otherwise, you will need to talk to your technical colleagues.

If you check this, the criteria will be inserted into the inquiry mail if below you use a button titled "Get quotation".

If you cannot sufficiently clarify your requirements, you may want to get technical consultancy from RP Photonics.

3. Find suppliers

We suggest three steps:

  • Below, you can find our list of suppliers for periodically poled nonlinear crystals. Use the checkboxes to mark possibly suitable suppliers.
  • The selected suppliers will appear below this list, along with your list of specifications. You can then indicate which specifications they meet according to your research.
  • Based on the results, you can finally choose a supplier that is hopefully a good enough fit.

periodically poled nonlinear crystals

Periodically poled lithium niobate (PPLN) crystal is a type of nonlinear optical crystal with distinguished high conversion efficiencies and a wide transparency range of 0.4–5 μm. The 5% MgO doping in LiNbO3 improves the damage threshold of the PPLN to a significant extent and broadens its phase-matching bandwidth. MgO:PPLN crystals exhibit a unique quasi-phase-matching (QPM) phenomenon, which allows the utilization of a higher nonlinear coefficient than in the case of birefringent phase matching

Shalom EO offers standard and off-the-shelf MgO:PPLN crystal and waveguides for SHG of 976 nm to 2100 nm and for various up-conversion and down-conversion applications including DFG, SFG, OPO, and OPA. Different dimensions, MgO concentrations, and AR coatings are available for selection.
