1. Absorption consumption.
This loss is caused by the inclusion of metal impurities and OH absorption light in the core, with a focus on the absorption of infrared and ultraviolet spectra.
2, dispersion consumption.
Dispersion is also a major factor in the laser loss of fiber laser marking machine, mainly caused by waveguide dispersion, material dispersion, and inter-mode dispersion, and the loss caused by these three aspects is not the same.
3. Scattering consumption.
Scattering is a phenomenon caused by the different atomic densities in various materials marked, resulting in different degrees of fluctuations, and then rapid condensation resulting in uneven density.
Presumably, many users who have operated the laser marking machine have certain insights into the marking machine red light indication system, a fiber laser marking machine laser marking machine production must include the red light indication system, here is often called red light adjustment, but red light adjustment has many functions, but also for the laser marking machine identification positioning plays a vital role, red light adjustment role mainly includes the following three points:
1. Red light adjustment as indicator light, used in the adjustment resonant cavity optical path.
2. Red light can also be used as the focus point of the laser marking machine, that is, the indication of the marking distance.
3, as the laser marking machine marking positioning with the indicator light, according to the different marking software, can be divided into marking center point indication, marking pattern length and width range indication, marking pattern overall simulation indication and other indication methods.
