…such as metal welding. In these heavy industrial applications, raw power is more
important than beam quality, and for many years, these lasers were lamp-pumped. But the ever-increasing power and lifetime characteristics of laser diodes
are causing these lasers to switch to diode…

…particularly suitable for welding thin, dissimilar and/or temperature-sensitive materials. Additionally, SmartWeld+ simplifies welding workpieces with poor fit-up tolerances since it allows the width and depth of the weld seam to be controlled independently of the focused laser spot size. Together,…

marking, cladding and ablating which require a certain intensity profile and beam contour for the process to work
properly beyond just the laser power or power density.
In many applications, it is required to focus the laser beam in order to create very small spot

…fiber laser wavelength of ~1 µm,
as compared to CO2 laser wavelength of 10.6 µm.
Fiber lasers, in particular, match the requirements of keyhole welding extremely well. They
typically offer output powers in the range of 500 W to 10 kW, and can readily achieve
focused spot sizes in…
