Quantum Cascade Lasers

Low Dissipation Lasers

Among the wide offering of lasers from Alpes Lasers, some stand out for their particularly low energy dissipation. For example, these lasers with less than 1W of total dissipation are immediately available:

Wavelength of interest
1900 cm-1
1900 cm-1
1900 cm-1
2209 cm-1
2226 cm-1
2325 cm-1

Other wavelengths are also available with low dissipation; be sure to contact us with any inquiry!

These lasers are particularly interesting for applications in harsh thermal environments or for applications where high electrical power is not readily available.

In a recently published Optics Express article, the Alpes development team discusses the research that was required to develop such low-dissipation lasers, and in particular the optimization of facet reflectivity which allowed both low-dissipation and high-power lasers to be produced from the same underlying material.

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.
