Making Good Purchase Decisions

As the most professional photonics purchasing portal, RP Photonics helps you to not only to find all relevant suppliers (not limited to our advertisers), but also to make good purchasing decisions.

NEW: Structured Decision Process

Purchasing involves a lot of responsibility. 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.

Our article on best practices for purchasing and another one explaining this tool give you valuable insights.

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 buy.

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 mid-infrared laser sources. 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 mid-infrared laser sources. 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.

This extension complements the compact 50fs-thulium-doped ultrafast fiber laser system and provides a high-power frequency comb in the mid-IR. The ultrafast mid-IR pulses are achieved through intra-pulse difference-frequency generation, which guarantees passive carrier-envelope-offset stability. The complete frequency-comb nature of the source can be achieved by controlling and stabilizing the fundamental pulse-repetition frequency of the driving laser.

mid-infrared laser sources

ORPHEUS-MIR is an optical parametric amplifier (OPA) optimized for the efficient generation of broad-bandwidth MIR pulses. The laser system provides ultrashort pulses in the tuning range of 2.5 – 10 μm and reaches up to 15 μm with a narrow-bandwidth extension. Due to the novel system design, ORPHEUS-MIR provides < 100 fs pulses directly at the output. Signal and idler outputs are available simultaneously. The system architecture is well suited for high-energy and high‑power PHAROS and CARBIDE femtosecond pump lasers. ORPHEUS-MIR serves as an excellent high-repetition-rate source for spectroscopy, such as two-dimensional infrared (2D IR) and vibrational sum-frequency generation (SFG) spectroscopy. Combined with the narrow-bandwidth output of SHBC, it forms a compact laser system for SFG measurements, covering most of the MIR spectrum in a single shot and providing high spectral resolution. In addition, its high output stability is the key to fast and high-quality SFG imaging. Furthermore, for MIR applications requiring CEP-stable pulses, ORPHEUS-MIR provides a unique CEP-stable option in the complete 2500 – 15000 nm range.

mid-infrared laser sources

Our mid-IR tunable broadband light source is fully automated and designed to be highly customizable to deliver turn-key solutions meeting your specific needs. It is based on a 1 µm pump laser operating at 76 MHz, which drives an optical parametric oscillator (OPO, Levante IR fs).

The OPO generates signal and idler in the range of 1.32 µm to 4.8 µm. Both beams can be mixed in a Difference Frequency Generator (DFG, HarmoniXX DFG), providing access to wavelengths up to 15 µm. Moreover, such a light source can be extended with additional APE devices, such as wavelength converters, pulse pickers or pulse slicers, to further enhance its capabilities in terms of wavelength range, repetition rate adjustment or spectral bandwidth narrowing.

mid-infrared laser sources

The spectral region between optics and electronics lying in the mid-infrared is difficult to access. Nevertheless it is of great spectroscopic interest because it hosts the majority of molecular finger prints: important vibrational modes with energies in the spectral range of 670 cm−1 to 3400 cm−1 can be accessed by exciting the sample at wavelengths of 3 μm to 15 μm.

TOPTICA’s ultrafast fiber laser FemtoFiber dichro midIR generates powerful radiation tunable between 3 μm – 15 μm that is ideally suited for spectroscopy and (nearfield) microscopy applications. Based on difference frequency generation (DFG) of two optically synchronized laser pulses at tunable wavelengths of 1 – 2 μm a highly stable broadband emission of approximately 400 cm−1 is generated.

TOPTICA’s continuous wave TOPO generates precise radiation tunable between 1.45 – 4+ µm with very narrow spectral width and extremely fine tuning, rendering it the ideal tool for spectroscopy of gas-phase molecules. The TOPO is a continuous wave optical parametric oscillator (OPO). As in DFG, a pump source and signal photons are mixed in a nonlinear crystal to perform downconversion, but in the TOPO the signal is self-generated by the efficient OPO process.

The Stuttgart Instruments Alpha is an ultrafast and fully wavelength-tunable frequency conversion system in an ultra-compact and completely passively stable system based on revolutionary parametric oscillator design which guarantees outstanding stability, reproducibility and shot-noise limited performance.

The revolutionary design of Stuttgart Instruments Alpha, characterized by outstanding low noise and passive long-term stability, is based on the fiber-feedback optical parametric oscillator (FFOPO) technology and results in outstanding performance and high flexibility at the same time.

The Alpha covers a gap-free rapid tunable spectral range from 700 nm to 20 µm wavelengths, while maintaining high output power up to the Watt-level with femto- or picosecond pulses at several MHz pulse repetition rates. It provides multiple simultaneously tunable outputs with a selectable bandwidth from a few to 100 cm-1. Shot-noise limited performance above 300 kHz, passive spectral stability (< 0.02% rms) and wavelength-independent stable beam pointing (< 30 µrad) enable excellent sensitivity. In addition, each Alpha is equipped with a user-friendly ethernet and Wi-Fi interface and a matching graphical user interface (GUI) as well as easy to access API interfaces for e.g. LabView, Python, C++.

Typically, the Alpha is pumped by an ultra-low-noise Primus pump laser, which provides more than 8 W average output power at 1040 nm wavelength and 450 fs pulse duration at 42 MHz repetition rate. In addition, the Alpha can be operated with other pump lasers around 1 µm wavelength and enough power.

Due to our modular platform, the Alpha can be adapted and optimized for various applications and is particularly suited for spectroscopic applications requiring a robust and reliable tunable radiation with low noise.
