This article provides the basic information about how and why lasers work.Over 60 years have passed since the first demonstration of a laser in 1960. After the initial spark of interest, lasers were for a while categorized as “a solution waiting for a problem,”...Photonics HandbookLaser Beam Measurement: Slit-Based Profilers for Pulsed Beams: Although slit-based profilers were designed to measure continuous-wave (CW) lasers, they can also work for pulsed-mode lasers.Measuring pulsed-beam lasers has generally required the use of a CCD array profiler. This is a reasonable solution for low-power lasers in the UV and visible wavelength range, but these require...Photonics HandbookBeam Diagnostics: Meeting the Need for High Quality: Whether the application is scientific, commercial, industrial or medical, beam diagnostics has become an integral tool for users and manufacturers of lasers and laser-based systems. There is an increasing need to achieve, monitor and maintain higher quality beam characteristics to meet the demands of more sophisticated laser designs and tighter laser process tolerances.For any discussion of laser beam diagnostics, it is first necessary to define some terms that characterize beam properties. Broad definitions can include measurements of laser energy or power,...WHITEPAPERSPhotonics.com 12/10/2021Compact, Self-contained Pulsed Lasers Expand Capabilities in LIBS ApplicationsLIBS analysis is now being adopted as an attractive technique in a wide range of industrial applications: from sorting recycled metals to identifying future mining areas.
