Request InfonLIGHT Inc.A line of high-brightness, single-emitter diode lasers in the 650- to 690-nm range has been announced by nLight Corp. The devices rely on proprietary nXLT technology and are available in either C-mount or HHL packages. They feature 1.5 W of optical power from a 150-μm emitter width at 665, 680 and 690 nm. The company says that it was able to increase the rated power by 50% without sacrificing reliability or reducing lifetime. Applications include photodynamic therapy and DNA sequencing. Specific combinations of wavelength, power and emitter width can be customized for OEM applications.See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Mar/Apr 2023 IssuePhotodiode PhotodetectorsExtended 2.6-µm Cutoff InGaAs Photodiode Photodetectors from Marktech Optoelectronics Inc. provide high sensitivity, high speed, and low noise for nondispersive spectrometers, pyrometers, and...Photonics Spectra July 2022 IssueGreen Laser DiodeThe PLT5 522EA_Q green laser diode from ams OSRAM is a cost-competitive replacement for red lasers in applications such as leveling, scanning, biosciences, and dot projection.
