By Alexander Laskin Introduction Powerful multimode fiber lasers, as well as fiber‑coupled solid-state and diode lasers, are widely used in industrial laser applications, and beam shaping of these multi-kW sources is of great importance to improve technologies like welding, metal sheet cutting, cladding, hardening. Due to physical properties of light propagation in multimode fibers, these […]

Comparison of 1 Micron Transmissive Optical Materials for High Power Lasers
By: Steve Rummel, Gary Herrit, Alan Hedges II-VI Infrared One of the problems that high power fiber, direct-diode, and disk laser users experience is thermal lensing of their beam delivery optics and debris windows. This is placing increased demands on the optics used in 1 micron laser beam delivery systems. Direct-diode lasers, meanwhile, continue to […]
