General

The development of new laser diodes operating in the 1.6÷3.8 mm range and based on III-V solid solutions provides a very attractive tunable source of radiation with high spectral purity.These lasers meet the requirements of high-resolution molecular spectroscopy.

2.7-3.8 mm Laser Diodes

The key elements of superhigh resolution laser spectrometers are tunable semiconductor lasers. Earlier lasing frequency was usually tuned only by heating. Besides this quite slow process our tunable diode lasers for spectral range 2.7-3.8 mm provide controlled by current wavelength shift in single-mode lasing towards the shorter wavelengthbased on nonlinear optical phenomena.Quantum-mechanical nature of this mechanism provides high-speed operation of tuning (approximately 10-12c).
Because of the speed of tuning of these lasers, their use is also extended into the sphere of study of the kinetics of chemical reactions, monitoring of fast processes and detection of molecular ions and short-lived radicals. 
Below you can see two examples how our laser diodes were applied in Tunable Diode Laser Spectroscopy
