Overview of UniMir 13.4µm – 746 cm-1: Narrow Linewidth Gas Sensing QCL

Perfect for measuring xylene and propane monitoring, this UniMir 13.4µm (746 cm-1) model is a single-mode DFB QCL, operating in CW mode with 5mW output power (with the base plate of the HHL-package at 20oC). The full tunable range is ~3cm-1, while the continuous tuning range, free from ‘mode hopping’ is >1cm-1.

The groundbreaking UniMir line of long-wavelength, single-frequency DFB QCLs from mirSense are now commercially available in a sealed High Heat Load (HHL) package, with integrated collimating lens, thermistor, and thermoelectric cooler (TEC), well suited for integration into systems, or as a stand-alone turnkey system for R&D and detection applications. These lasers, operated in CW or in pulsed mode, emit a maximum power of 5 to 10mW (<15µm) at room 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 maintaining single longitudinal mode operation. The technology’s versatility allows them to address any wavelength between 10 and 18µm in CW and up to 21µm in pulsed mode, opening the way for high-resolution spectroscopy applications in this spectral range, notably for the detection of BTEX, but also CH3I, HCN and many other compounds.
