Request InfoSpectra-PhysicsOptimized for micromachining of transparent, brittle materials, a new industrial femtosecond laser from Spectra-Physics Inc. (a Newport company) may be used in display manufacturing. Spirit ClearShape (Spirit CS) uses the company's patent-pending ClearShape laser process for cutting curvilinear and closed shapes in chemically strengthened glass, unstrengthened glass and sapphire. The process requires an average output power of <4 W. At cutting speeds up to several meters per second, it yields <0.1-μm edge roughness and as-cut bending strength up to 700 MPa for chemically...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra October 2020 IssuePulsed Green Fiber LaserThe Spectra-Physics® SPFL 532-40 pulsed green fiber laser from MKS Instruments Inc. features >40-W output power and up to 180 μJ pulse energy.

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.
