Request InfoAlfalume Inc.SANTA CLARA, Calif., March 8, 2023 — Developed in partnership with Innolume, Alfalume's O-band high-power InAs/GaAs Quantum Dot DFB lasers operate at a power level of 250 mW at 85 ºC, without requiring thermoelectric coolers, which can be split into four or eight channels for 800 G and 1600 G DR8 Modules. The lasers have a power efficiency of 20% at 105 ºC and can operate efficiently up to 150 ºC. They are insensitive to feedback up to -15 dB, enabling operation without an optical isolator, and they feature high SMSR, greater than 55 dB. They also feature low relative intensity noise below -155 dB/Hz.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra August 2022 IssuePortable 3D ScannersThe HandySCAN™ 307|Elite and HandySCAN™ 700|Elite high-performance scanners from Creaform feature blue laser technology.

Enter Class 1 laser products — lasers that are so safe that the user doesn’t require specific laser safety training or protective eyewear. Some precautions still exist, though.When purchasing an industrial laser system, the astute buyer will look for a Class 1 laser product — a system where the laser beam hazard is completely enclosed and there is no potential laser...Photonics HandbookIndustrial Lasers: An Introduction to Process Qualification: The step from successfully demonstrating a new laser process on a limited number of samples under laboratory conditions, to scaling that process up for high-volume industrial use is a big one. In particular, it’s necessary to determine how variations in process parameters affect end results, so that acceptable process input and operating ranges can be determined.Materials processing with lasers is actually a broad term for a diverse range of applications. The major categories of these uses, and the lasers that service them, are summarized Table 1.
