Purchasing Advisor for Periodically Poled Nonlinear Crystals (original) (raw)

Find all you need for professional sourcing of periodically poled nonlinear crystals: a comprehensive expert-curated directory of suppliers, scientific and technical background information, and an interactive AI-based tool with guidance for a structured decision process.

NEW: Not only hardware can be listed here, but also consulting, software, training on periodically poled nonlinear crystals, etc. – see the "offer types" below.

🌐 You appear to be visiting from North America. Many listed suppliers are based in this region, making the RP Photonics Buyer's Guide highly relevant for your needs.

Purchasing high-value photonics products is a substantial responsibility. Using a structured decision-making process and high quality supplier data helps a lot:

Find all relevant suppliers (not limited to advertisers).
Our interactive tool conveniently assists you in defining and applying your application-specific requirements.

Note that purchasing decisions based on just a few randomly picked suppliers and without carefully defined specifications are risky; therefore, we strongly recommend using our data and tool. See also:

Go through the process:

1. Understand the technical background

2. Define your requirements

It is essential to fully understand and clearly define your requirements before you purchase.

We recommend that you develop a list of clear specifications according to your specific needs, against which you can later check the suitability of found product offers:

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.

This list is for your own preparation, and can later (possibly in modified form) be used for quotation requests to suppliers.

I think that I am sufficiently informed about our requirements.

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

I consider the above list of specifications to be sufficiently complete, clear and accurate.

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

Insert these criteria when creating inquiry mails to suppliers with the buttons "Get quotation".

You find these buttons in the supplier list below or under "3. Find suitable suppliers".

3. Find suitable 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. (You should finalize your specifications before doing this.)
Based on the results, you can finally choose a supplier that is hopefully a good enough fit.

Comments, e.g. reasons for your choice, or things which still need to be checked:

4. Document the decision process

It is essential to document your purchasing process, not only its result (chosen supplier):

You will find it easier next time.
If something goes wrong, you can defend your decision by showing that you properly considered all important aspects. Or you see what needs to be done better next time.

Our interactive tool makes it easy: Fill out the form, and in the end print it to a PDF. Note that the document will show all sections (including those not currently shown on the screen), while omitting some irrelevant details such as the page navigation.

⚙ hardware

GWU offers periodically poled lithium niobate (PPLN) crystals with highest quality for quasi-phase matching (QPM). The sophisticated manufacturing process allows for the engineering of PPLN crystals tailored for arbitrary frequency conversion processes for full spectrum applications, covering SHG, SFG, THG, DFG, OPG, OPA and OPO. Many standard crystals are available off-the-shelf for fast shipping. PPLN crystals can be combined with waveguide structures to enhance the conversion process, yielding high efficiency especially in weak light applications. For maximum user convenience, our PPLN crystals are available in a robust and ready-to-use package: the PPLN Mixers. Besides being plug & play devices, the Mixers are widely customizable in wavelength and are available in free-space or fiber-coupled configurations. Product-specific web page

⚙ hardware🧩 accessories and parts🧴 consumables🔧 maintenance, repair📏 metrology, calibration, testing💡 consulting🧰 development

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. Product-specific web page
