Buying Narrow-linewidth Lasers

Top-level product category: lasers and laser amplifiers

More general product categories: single-frequency lasers

More specific product categories: single-frequency lasers

Related product categories: frequency-stabilized lasers, optical frequency standards

Narrow-linewidth lasers emit light with very narrow linewidths, providing high temporal coherence. These lasers are crucial for applications in laser spectroscopy, optical metrology, optical sensors, and holography. Single-frequency lasers often achieve sub-Hertz linewidths for extreme precision.

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 narrow-linewidth lasers. 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 narrow-linewidth lasers. 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.
