Request InfoCoherent Inc.Coherent Inc. has unveiled two optically pumped semiconductor lasers for photocoagulation treatment of wet-form macular degeneration and of diabetic retinopathy. The OPSL-532-5 is a 5-W green laser with output of 532 nm, while the OPSL-577-3 delivers 3 W of yellow output at 577 nm. The wavelength of the latter device is precisely matched to the main absorption peak of oxygenated hemoglobin, thus providing a higher degree of tissue selectivity. The laser technology can be designed to operate at any arbitrary visible or NIR wavelength and output power, and it facilitates modulation of the light...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra April 2023 IssuePolarization-Stable VCSELA multimode vertical-cavity surface-emitting laser (VCSEL) with stable polarization from TRUMPF Photonic Components GmbH features surface gratings to enable stable polarization for high-illumination...Photonics.com 10/16/2023VCSEL Array BoardsThe CC200-Tx Series from Metrio Sensors Inc. are VCSEL array boards that are connected to their own drivers.
