Rofin-Sinar Laser GmbHRofin-Sinar Laser GmbH introduces the 1500-W Rofin DL 015S diode laser. It can focus to a spot measuring 1.2 x 1.2 mm, making it practical to incorporate the laser into a 1.5-mm-diameter fiber optic beam delivery system. The DL Series lasers are available in powers from 750 to 2500 W and are suitable for hardening applications that require spot sizes from 4 to 15 mm. The compact lasers have a diode lifetime of more than 10,000 h.See full productRelated content from Photonics MediaPRODUCTSPhotonics 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,...Photonics.com 8/31/2022Broadband and Wide-angle Laser Line MirrorsBroadband and Wide-angle Laser Line Mirrors from Knight Optical Ltd. feature an Ion Beam Sputtered (IBS) coating to meet the demanding requirements sought by laser system manufacturers. ...Photonics Spectra January 2023 IssueInGaAs Quad and Array PhotodiodesInGaAs quadrant and array photodiodes from Marktech Optoelectronics Inc. are designed for laser alignment and position sensing applications.
