Request InfoHamamatsu CorporationHamamatsu’s pulsed QCL module (part number L14147-1278-02) combines a pulsed QCL, pulse driver, and a TE-cooler controller into a housing approximately 185 mm x 127 mm x 70 mm in size. The QCL emits pulsed mid-infrared radiation at 7.82 µm (about 1278 wavenumbers), and has a typical output power of 100 mW. The QCL module requires a 24 V DC power supply, and it can be easily and remotely controlled via an Ethernet connection. Suitable applications include MIR absorption spectroscopy for trace gas analysis and emissions monitoring.See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Jul/Aug 2023 IssueDual-Comb SpectrometerThe IRis-C spectrometer from IRsweep utilizes dual-comb spectroscopy and quantum cascade laser frequency combs to offer a combination of high speed, high signal to noise ratio per time, as well as...BioPhotonics Jan/Feb 2024 IssuePortable Wideband LaserThe SLP-1000 from SuperLight Photonics is a portable wideband laser.
