Marking application
Pulsed fiber laser, with its excellent beam quality, reliability, longest maintenance-free time, highest overall electro-optical conversion efficiency, pulse repetition frequency, minimum volume, the easiest and most flexible way to use without water cooling, the lowest Operating costs make it the only choice for high speed, high precision laser marking.
A fiber laser marking system can consist of one or two fiber lasers with a power of 25W, one or two scanning heads for guiding light onto the workpiece, and an industrial computer that controls the scanning head. This design is more than four times more efficient than splitting onto two scan heads with a 50W laser. The maximum marking range of the system is 175mm*295mm, the spot size is 35um, and the absolute positioning accuracy is +/-100um in the full marking range. The focused spot can be as small as 15um at 100um working distance.
Material handling application
The material processing of the fiber laser is based on a heat treatment process in which the material absorbs the laser energy. Laser light with a wavelength of around 1 um can be easily absorbed by metals, plastics and ceramic materials.
Material bending application
Fiber laser forming or bending is a technique used to change the curvature of a metal or hard ceramic. Centralized heating and rapid self-cooling result in plastic deformation in the laser heating zone, permanently changing the curvature of the target workpiece. Studies have found that laser-treated microbending is much more precise than other methods, and this is an ideal method for microelectronics manufacturing.
The application of laser cutting With the increasing power of fiber lasers, fiber lasers have been scaled up for industrial cutting. For example: micro-cutting stainless steel arterial tubes with a fast chopping continuous fiber laser. Due to its high beam quality, fiber lasers can achieve very small focus diameters and the resulting small slit width is refreshing the standards of the medical device industry.
