Alpes Lasers SA is a Swiss company specialized in the development and fabrication of advanced light sources in the infrared (IR) spectral range. Our company was founded 20 years ago and was the first company in the world to commercialize Quantum Cascade Lasers (QCLs). These lasers are becoming increasingly important in chemical sensing applications based on IR spectroscopy and in directional infrared countermeasure (DIRCM) applications.

Our company is currently working on the development and launching the production of novel product lines, including high power QCLs, optical frequency comb QCLs, tunable lasers, and various laser systems.

Our company has the privilege of participating to numerous European research projects.
