FLC is a partner of mirSense, a supplier of off-the-shelf Industrial Quantum Cascade Lasers (QCL) and QCL-based spectrometer modules for Industrial & Defense applications. For the first time, based on an InAs-technology, single frequency DFB lasers are commercially available in the wavelength range from 10-17µm and output power of 5 – 10mW. The laser is mounted on a thermoelectric cooler inside a sealed High Heat Load (HHL) package integrating a collimation lens and a thermistor to readout the laser chip temperature. By controlling the chip’s operating temperature through the Peltier element inside the laser’s package, customers tune the emission wavelength without mode hopping while keeping a longitudinal single-mode operation.
