Request InfoToptica Photonics AGToptica Photonics AG has introduced the TA-SHG 110, a CW frequency-doubled laser that emits UV light. It is based on proprietary tapered amplifiers, it achieves frequency doubling via a resonant enhancement cavity in bow-tie configuration, and it uses an external cavity diode laser. Tunable between 329 and 336 nm, it can operate at >100 mW and is spatially and spectrally single-mode. It can be used for Raman spectroscopy, gas analysis and interferometry.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra October 2023 IssueUltraviolet LasersThe next generation of low-cost Matrix ns-pulsed UV lasers from Coherent Corp. are designed for high-contrast marking applications in various industries such as consumer goods, industrial...Photonics Spectra January 2024 IssueCompact Single-Frequency LasersThe 445-nm and 447-nm TopMode lasers from TOPTICA Photonics AG are single-frequency diode lasers made for high-resolution Raman spectroscopy, microlithography, multi-wavelength digital holography,...BioPhotonics Mar/Apr 2024 IssueLaser Microdissection SystemThe Accuva Cellect from Laxco Inc. is a laser capture microdissection (LCM) system designed to enable isolation and capture of single cells with accuracy for improving research and analysis.
