Founded by Jerôme Faist, a co-inventor of quantum cascade lasers, Matthias Beck und Antoine Muller in 1998, Alpes Lasers became pioneers in advanced light sources, especially Quantum Cascade Lasers (QCLs). Already in 2001 Alpes Laser started to the series production of QCLs. Since then all products were developed for industrial environments and requirements.
Almost infinite narrow line width facilitates high resolution gas spectroscopy and photoacoustic experiments. Can be Peltier cooled due to high wall-plug efficiency and low dissipation.
Narrow bandwidth suitable for gas phase spectroscopy. Compact housing for miniaturized sensors. For industrial applications the use of the HHL housing is recommended.
Fabry-Pérot lasers provide broad band emission with several laser modes and high optical power. The emission spectrum is nearly unaffected by temperature changes. FP-QCLs are ideal in applications with broadband and powerful MIR light source.
These lasers are Fabry-Pérot lasers designed for maximum width of the gain profile. Thus, the spectral range from 6 to 12 µm can be covered with a few lasers. If coated with an anti-reflection coating, broadgain illuminators build the core of external cavity lasers (EC-QCLs). These broad band sources provide a constant spectral power density and a high optical power.
Broad band emission with several modes and high power. Maintenance-free alternative for CO2-Lasers.
Multi-mode THz-laser with high optical power.
Can be used with LN2 or sterling cooler. i-mode THz-laser with high optical power. Can be used with LN2 or sterling cooler.
ALPES offers bare QCL chips but also chips in different housings.
As Standard the following variations are availsble:
- HHL "high heat load housing" with AR-coated window or lens; or with fiber coupling.
- LLH "laboratory housing" (only with plain window - uncollimated). The advantage is that the user can use the housing for different QCL-chips and exchange them by his own.
- TO3 TO3-can with AR-coated collimation optic.
