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.
You will get efficient and thoughtful service from JCZ.
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 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.

Product-specific web pageORPHEUS-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 – nm range.
Product-specific web pageThe 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 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.
Product-specific web pageOur 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.
Product-specific web pageHi all.

Ortur got back to me about my inquiry as to the OLM3 (400x400) + 20w + 1.6w + platform + air assist. 24v
They say they dont have the 1.6w So I asked about IR or 5w from them or other manufacturer that would suit with no mod’s needed.
I thought I’d ask here because I fear another long list of questions with vague answers.
would the 10w at 0.05x0.1 advertised spot be ok to start learning fine detail engraving?..its a budget thing! but may OPT for an upgrade asap.
Does anyone know if the OLM3 is 8bit or 32bit…I had assumed 32 but came across an advert for 32bit upgrade board & I cant find the info on their site…One less upgrade to get me dialed in for detail.
Amazon list the shipping + tax to Ireland as over 300 euro. Would I buy equal quality in europe and avoid the import tax.
All opinions will be received as such and not as advice or responsibility!
Thanks
Firstly, sorry for hours not answering, my buddy had a little send of for his son going to college in engerland…had to attend.
Thanks Mike, I hadn’t consciously related x to 0.05 & y related to 0.1…now I do!
The 1:2 didnt seem that outa whack at the time given the fog of purchasing and that its pretty small relative to some of the long recktangles on the market…maybe if I did the 45deg adjust it might not be to bad.
The 20w is for cutting and a bit of speed and bigger engraving, at 0.08x0.08 as (advertised) seems reasonable for that type of work and possibly more squarish.
I like to blend the detail into the bigger work…thinking about the 8ft x 4ft bed which lauches any day now…it might sound odd but I see potential.
I might be better off just playing with the 20w and getting used to things and look into something a bit custom asap.
Its more moving toward fine fine detail that Im looking at right now because its a different level and market.
Ah cool, I spent a week or so looking at those and quite liked them, also warehoused in europe which is handy.
I think I was tempted away by the k1 frame being 40x40mm to carry a k30w and a 5w from lasertree…but 23 emails in and still not much wiser, I went to have a chat with ortur…I was as far as asking LT for bank account details for transfer but heard no more from them…I think it was voltage and maybee board incompatibilitys that they didnt want to talk about. Im kinda insistant about knocking the most out of one strong frame…that might be my problem but double the frames is half the quality in my mind.
The Ortur LU 20A is 0.08x0.08(advertised) but the import tax eats up a wee chunk of the funds for the opt6w…if its Square!
Found this on the web:-
The pictures tell a lot about dot dimm’s but I wonder was there something else mechanical going on at abou the 4 o’clock area in the right hand picture.
Is this a good example of the difference between Co2 & diode?
I did this with an old 5w module…
Remove the module from the gantry. Set the power at about 10% and point it at a wall about 6’-10’ away. You will then see the true pattern of the laser beam shape. It is definately not a dot or oval.
Not for a 20w laser, which is where they try to focus 4 diodes to 1 spot. In my opinion, they understated the size.
