Packaging Options

QCLs are fragile semiconductor chips with a width of 400 microns and a length varying between 0.75 mm and 6 mm. To produce light, they must be mounted (soldered) on a heat carrying substrate and electrically connected.

Alpes Lasers offers QCLs in a variety of packages, which are described in more detail below as well as in the manual.
