The lasers work at room temperature with a built-in thermoelectric cooler for temperature control and stabilization.  They can be operated in pulsed or continuous wave (CW) mode. The short pulse mode (typically 20 to 500 ns) is preferred for power QCLs, that can emit 1 to 2 W of average power at a typical duty-cycle of 50%. Single mode lasers rely on a patented distributed feedback (DFB) technology and exhibit typical output powers of 5 mW, well suited for infrared spectroscopy applications. They are tuned by changing the internal QCL temperature or driving current. In CW, the tuning range is typically 2 cm-1 with a narrow linewidth (<100 MHz) well suited for high resolution spectroscopy. With short-pulse operation, the tuning range and operating temperature range can be significantly increased, with linewidth still adapted to the photoacoustic spectroscopy implemented in our gas sensors.

High indexBall lens

When a laser diode's fast axis beam divergence exceeds 60 degrees, a high refractive index acylindrical plano-convex collimating lenses are the best solution. These side lobes-free lenses are offered in a short and long working distance version.

The QCL active region is based on a carefully quantum-engineered heterostructure, made of hundreds of nanometer-scale semiconductor layers, that allows to create a specific electronic density of states which leads to optical gain and lasing between cascaded electron subbands. The particularity of this concept is that the emitted wavelength does only depend on the layer thicknesses, not on the constituent materials. As a consequence, the same technology is capable of producing lasers in a very broad spectral range (λ from 3 to 20 µm). This is however a complex technology, that requires a very demanding control of all the fabrication steps, from the quantum design, to the multi-layer material growth, the device fabrication, the thermal management and the optical control of the emitted light.

The photoacoustic effect applied to gas is today one of the most sensitive laser spectroscopy technique for local detection. Using laser light sources whose wavelength matching the spectral fingerprint of specific and chosen molecules to identify, an acoustic signal can be obtained if the molecule is present in the analyzed sample.

An important technique to increase the acoustic signal consists in hosting the photoacoustic effect within a resonant gas cell. Gas cells is therefore geometrically designed to display a resonance behavior at a specific frequency , resulting in an improved sound pressure level characterized by the resonance factor.

The present maturity of QCLs offers unprecedented possibilities for defense applications or gas sensing through molecular spectroscopy applications that were previously limited by the lack of suitable laser sources.
