Kvanttilaser

Kvanttilaser is a company that develops and manufactures quantum cascade lasers (QCLs). These are semiconductor lasers that emit infrared light, a property that makes them useful in a variety of applications. QCLs differ from conventional diode lasers in their operating principle. Instead of relying on electron-hole recombination, they use intersubband transitions within a specially engineered multi-layer semiconductor heterostructure. This design allows for greater flexibility in tailoring the emission wavelength.

The company's focus is on providing high-performance QCLs for demanding markets. Their products are utilized in areas such as gas sensing and spectroscopy, where precise detection of specific chemical compounds is crucial. This includes environmental monitoring, industrial process control, and medical diagnostics. The ability of QCLs to emit in the mid-infrared and far-infrared regions of the electromagnetic spectrum is particularly advantageous for identifying molecular fingerprints of various substances.

Kvanttilaser's technological expertise lies in the precise fabrication of these complex semiconductor structures. The development of QCLs requires advanced epitaxy techniques to control the thickness and composition of the numerous layers. The company aims to deliver lasers with high power output, narrow spectral linewidth, and stable operation, meeting the stringent requirements of scientific and industrial users. Their contribution is in advancing the accessibility and application of quantum cascade laser technology.
