Side-pumped laser marking machine
core laser element, one of many single LD pumping. That part has strict requirements to get installation process. For the early Japan's advanced technology putting your unit together techniques the laser came out of the laser cavity, finally pass through the focusing mirror and make a focus to play a role of laser marking function.
Beam expander has the ability to change the laser beam diameter and divergence angle for the lens components. Laser beam emitted from the laser carries a divergence angle for laser noticing. Meant for laser processing only let the laser beam go through the beam expander and adjust by way of the beam expander then it change the lazer as a direct (parallel) hug you, last but not least we can obtain high energy density, smaller spot laser.
With the laser marking machine, we've got to use the laser beam expander to raise the degree of alignment of the laser beam to acheive long-distance marking effect.
Different multiples within the laser beam expander corresponding with lasers will present a better performance. Laser beam expander with the use of spatial filter will make non-symmetrical beam distribution in to a symmetric distribution, and additionally make more uniform distribution of one's.
Lazer expander and a focusing system formed after a long focal length, but being a matter of fact this is the short focus length. For the reason that that we want to get a long working space and compact focus spot. So that you can expand the laser beam is for the purpose to improve the light see quality. The coming processing laser beam expand are including focusing first thereafter collimated. The refocus should be to narrow the focus spot size to enhance the power density and to help you process better with laser observing.
