Quantum Cascade Lasers

Alpes Lasers SA introduces two new product lines to its line-up of Quantum Cascade Lasers. All are available in High Heat Load housing with collimated output and can be accompanied by appropriate drivers for optimal usage.



The HP-QCL High Power Sources have a minimum average power of 1 W and more than 9 W of peak power with a multi-mode spectral output. Devices centered around 2040 cm−1 (4.9 μm) are available from stock, and other wavelengths on demand. The dedicated driver for these high power lasers can be programmed internally or externally controlled through TTL signals with arbitrary pulse sequences.

These lasers can be used for free-space optical communications, energy deposition, illumination and IR countermeasures.


The QC-ET Extended Tuning Quantum Cascade Lasers feature an  increased wavelength scanning span through fully electrical control at constant heat sink temperatures, allowing wavelength ramps and dither over a range of more than 0.4% of the central wavelength (6 cm−1 at  1270 cm−1). Such an extended tuning range can be used for fast wide scanning and multi-species gas monitoring.

As a separate option, QC-ET devices are available with an AM/FM modulator. These lasers use independent inputs to control the wavelength and amplitude of the emitted light, enabling true AM and
FM modulation with minimal cross-talk, with the same fully electrical control of an extended tuning range.

More details on all these products can be read on the news to the right on your screen!

Come meet us and see out new products at Booth #1010 at the Photonics West 2015 Exhibition from Feb. 10th to Feb. 12th!

Extended Tuning DFB Sources


Alpes Lasers introduces a new class of Extended Tuning DFB-QCL, the QC-ET. These QC-ET use a dual current control to extend the mode-hop free tuning to more than 0.4% of the central wavelength (>6 cm-1 at 1270 cm-1). While the first laser input allows direct intensity modulation in the same manner as standard DFB lasers, the integrated heater current IT allows to offset the wavelength much faster than the temperature change of the heatsink temperature would do.

AM/FM modulators


Alpes Lasers introduces a new class of extended tuning DFB quantum cascade lasers (QC-ET) with AM/FM Modulator. Contrarily to standard DFB lasers, these lasers use independent inputs to control the wavelength and amplitude of the emitted light, enabling true AM and FM modulation with minimal cross-talk.
