The ThorlabsSC4500 is the world's first commercially available femtosecond-laser-pumped MIR Supercontinuum Source. This source emits over a wavelength range from approximately 1.3 μm to 4.5 μm (7700 cm-1 to 2200 cm-1) with >300 mW of average output power in a collimated beam. More than 110 mW of the output power is within the 2.2 - 4.2 µm (4500 cm-1 - 2400 cm-1) range, which overlaps with many gas absorption lines and other molecular signatures. The brightness of this source exceeds traditional Globars and even synchrotron sources by orders of magnitude.

Multi-Function Supercontinuum Fibre Laser SC-Pro from YSL Photonics

The SC-Pro from YSL Photonics is a supercontinuum laser with tunable MHz-range repetition rate and adjustable power. The spectrum covers the range from 400nm to 2400nm. It’s especially suitable for fluorescence lifetime imaging, nanophotonics, infrared spectroscopy and other fields when working at the condition of 25MHz 5W. When working at 1-5MHz, it offers pulse energies of more than a micro-joule, which is ideal for fluorescence spectroscopy, or STED imaging fields.

With its unique features, SC-Pro makes it possible to generate a supercontinuum source with low repetition rate, microjoule pulse energy and high repetition rate,100 nJ pulse energy.

Laser Quantum Venteon Few cycle/short pulse

Few-cycle, short laser pulses have a number of advantages for researchers. At a constant average power, short pulses have a higher peak power and the higher spectral bandwidth is important for spectroscopy, THz generation and OPCPA seeding application. They also benefit the study of ultrafast processes in such applications as pump-probe or time domain spectroscopy.

The Laser Quantum range of short pulse lasers produce the shortest commercially available pulse duration, typically below 5fs.
Venteon PULSE ultrabroad - Octave spanning spectral output with sub 5fs pulses
Venteon PULSE CP - CEP locked without additional spectral broadening
Ventoen PULSE OPCPA seed - Dual output for OPCPA amplifier


Laser Quantum Venteon OCPCA


The Laser Quantum venteon OPCPA provides a unique combination of a few-cycle pulse duration with a pulse energy in the µJ-regime at a high repetition rate. The excellent output stability, and the ability for a CEP-stabilised output, makes this amplifier the ideal source for nonlinear spectroscopy, high harmonic generation and applications in attosecond physics. In contrast to more commonly used Ti:sapphire amplifiers, the unique parametric amplification process of the venteon OPCPA gives rise to a much larger gain bandwidth which maintains the excellent few-cycle pulse duration through the amplification process.


  • Remote connection capability
  • CEPLoQ technology
  • Low actual and FTL pulse duration
  • CEP upgrade
  • Parametric amplification for broadband amplification
  • Microjoule pulse energy at MHz repetition rate
  • Two color output optically synchronized as product variation
  • Push button start of amplifier pump
  • Automatic Delay stabilization
  • Active beam pointing stabilization for long-term measurements
  • MHz repetition rate for good experimental statistics

Laser Quantum: Venteon amplification

Laser Quantum exclusively provides comprehensive solutions for the emerging market of OPCPA systems - the most direct approach for amplified high-power, few-cycle femtosecond laser pulses. Unlike for other commonly used amplification concepts such as Ti:sapphire-based multipass or regenerative amplifier systems, the parametric amplification process of Optical Parametric Chirped Pulse Amplifiers (OPCPA) features a much larger gain bandwidth and no gain narrowing and thus is ideally suited to support the bandwidth and pulse duration generated by the broadband VENTEON femtosecond systems.

Laser Quantum is capable of all the necessary technology required to realize a complete OPCPA system and proved its expertise, knowledge and competence by developing the world’s first commercial OPCPA.

As a solid basis of the OPCPA systems, we can provide a specialized seed laser system, the Venteon PULSE OPCPAseed, which features a dual laser output for both, ultra-broadband signal and additionally a narrowband pump seed @ 1030 nm. The interface of the narrowband seed can be adapted in terms of coupling (free-space or fiber-coupled), pulse energy (with or without pre-amplification) and filtering. 

For amplifying the narrowband pump pulses @ 1030nm we have developed an independent preamplifer solution. TheVenteon PULSE Preamplifier modules are designed for  amplifying low energy pulses (10 pJ) of the seed oscillator to significant higher power levels. All modules can of course be used as independent amplification modules for other laser systems around 1µm.

Using this unique front-end laser system, the Venteon PULSE OPCPA is the first complete commercial protoype OPCPA system that now allows for the generation of sub-8fs pulses with pulse energies of more than 5µJ at high repetition rates.

With the Venteon PULSE SPIDER and the octave-spanning compression mirrors, Laser Quantum can also supply the pulse compressing and accurate measurement of few-cycle pulses generated by OPCPA systems.  


Toptica Difference Frequency Comb (DFC) Inherently CEP-stable modular frequency combs

frequency combs

TOPTICA’s frequency comb product line is a modular system that supports a broad variety of applications. Three basic versions of the DFC are available: DFC CORE, DFC CORE+ and DFC SEED. All models use TOPTICA proprietary CERO-technology to achieve an unprecedented low-noise performance.

The DFC CORE and its high performance version DFC CORE+ come with a digital oscilloscope for beat monitoring and a GPS disciplined RF reference included. They both provide 4 or optionally 8 phase-stable outputs at 1560 nm.

Several extension modules are available that can convert the DFC CORE / DFC CORE+ outputs to any wavelength between 420 nm and 2200 nm. The extension modules can be upgraded at any time after purchase of the DFC CORE and are interchangeable between outputs.

In addition, beam combiner (DFC BC) and beat detector (DFC MD) units are available to provide RF beats between the DFC comb lines and cw lasers. The RF output signal of the DFC MD can be counted to determine the frequency of the cw laser. It also enables phase or frequency stabilization of the cw laser to the DFC using e.g. TOPTICA’s locking modules mFALC or DigiLock. In the DFC CORE+ version, the RF output signal can also be used to stabilize the DFC to the cw laser which serves as optical reference.

Such a DFC system can be combined with any of TOPTICA’s tunable diode lasers to achieve a complete, frequency referenced laser system including wavelength meter and counter all from one source.
