IR Laser Diodes
In August 1993 another dimension was added to our in-house production: A technology transfer from the Fraunhofer-Institut für Physikalische Messtechnik brought the complete production line of IV VI semiconductor lasers from Freiburg to Olching.
With an output power of at least 0.1 mW, the emission wavelengths of the diode lasers are between 3 and 20 µm. These lasers serve as important spectroscopic light sources for trace gas and isotope analysis in the laboratories of both universities and various industries.
The manufacture of these lasers is completely in our hands – from crystal growth to diffusion technology and from molecular epitaxy to photolithography and assembly. We record the spectral properties of the lasers on their corresponding mode charts only after they have gone through a rigid system of quality assurance procedures.

NIR Laser Diodes
The range of spectroscopic diode lasers has been continually expanded over the course of the past few years and now includes single mode VCSELs at 760, 794, and 850 nm as well as DFB lasers between 1.25 and 1.75 µm.
The latest addition to our SPECDILAS^® family is the quantum cascade laser. LASER COMPONENTS has specialized in the mounting and assembly of QCL chips and offers lasers between 5.5 and 12 µm in a standard TO can with TEC. A controller for industrial and lab use was specifically designed by us.

Spectroscopic Application Lab
Furthermore, we have added a laboratory for the production of IV VI IR diode lasers. This lab can be rented together with experienced personnel for measurements and feasibility studies. Spectroscopic measurements of the customer’s samples or of reference gases from LASER COMPONENTS can be performed with the help of PbSe or quantum cascade lasers in the range from 3 to 25 µm or 5.5 to 12 µm, respectively.
The high cost of buying a complete spectroscopic system is cushioned in this way. We gladly inform newcomers to high resolution spectroscopy about their options and possible fields of application.
