Purchasing Advisor for Autocorrelators

Find all you need for professionally buying autocorrelators: an interactive tool with a comprehensive and trustworthy directory of suppliers and expert guidance for a structured decision process with scientific and technical background information.

Top-level product category: icon detectors and measurements

More general product categories: pulse duration measurement devices

Optical autocorrelators are devices used to measure and characterize ultrashort laser pulses, providing information on pulse duration and shape. Different types, including intensity and interferometric autocorrelators, are employed in laser physics and photonics research to analyze and optimize laser performance.

Interactive Purchase Decision Tool

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

Go through the process:

1. Understand the technical background

It is important to sufficiently understand the technology before buying.

Use the comprehensive learning resources of RP Photonics:

If you need personal help, contact RP Photonics to get technical consultancy.

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 autocorrelators. 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.

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

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

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 autocorrelators. 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.

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.

autocorrelators

TUNDRA®, by UltraFast Innovations (UFI®), is a third-order autocorrelator, which serves as a highly sensitive diagnostic tool for laser pulse contrast measurements. Using third-harmonic generation, TUNDRA can distinguish between pre- and post-pulses. Its dynamic range reaches up to 14 orders of magnitude, sufficient for detecting even the tiniest parasitic pre- and post-pulses. The scan range is up to 3.8 ns, and pulse durations from <20 fs to 3 ps can be measured. It is available for 800 nm and 1030 nm but other wavelengths can be provided upon request.

TUNDRA is a fully automated device, serving as an invaluable tool for state-of-the-art characterization of ultrashort laser pulses. Its designed ensures that ghost pre/post pulses are avoided.

autocorrelators

Our compact ultrafast autocorrelator is used to characterize ultrafast laser pulses originating from Ti:sapphire and Yb:doped lasers. Featuring a built-in two-photon absorption (TPA) detector, this autocorrelator is ideal for measuring ultrafast femtosecond and picosecond laser pulses at wavelengths from 700 to 1100 nm. The highly sensitive TPA detector allows for measurements of ultrafast laser pulses with high sensitivity by eliminating the need for angle tuning of the SHG nonlinear crystal.

autocorrelators

APE autocorrelators are used to measure the pulse duration of femtosecond and picosecond laser systems. The technology is based on either second harmonic generation (SHG) detection or two-photon absorption (TPA) detection principle.

APE autocorrelator models:

  • pulseCheck: multitalent for any task
  • Mini TPA: compact and tuning-free
  • Mini PD: routine tasks with a fixed wavelength range
  • Carpe: first choice for multiphoton microscopy

autocorrelators

Femto Easy offers two different types of very compact and handy autocorrelators for ultrashort pulse characterization:

  • The ROC autocorrelator is a single-shot autocorrelator, thus it needs only a single pulse to measure its duration. It is very compact and extremely easy to use. It covers a wide range of pulse energies from a few hundred picojoules to a few millijoules, and durations from 5 fs to 10 ps. Also based on a single-shot architecture, the µ-ROC is the most compact autocorrelator ever built.
  • The MS-ROC autocorrelator is a multi-shot autocorrelator. It uses a particularly fast optical delay line to scan the delay, minimizing the measurement time. It can measure pulses with energies as low as 50 pJ, and with its fine-scan mode for durations even below 50 fs.
