Investigation on the mechanism of a new laser surface ...In the experiments of laser polishing Ti-6Al-4V alloy, Chen et al. also obtained the similar surface structures. They investigated the influence of laser power P, scanning speed v scan, and beam diameter D (focal offset) on h 1exp and w exp. And the evolution trend of the h 1exp and w exp obtained by Chen et al. is consistent with this study.

The Ultimate Guide to Fiber Laser Cutting | MachineMfg

Laser cutting can achieve better cutting quality due to the small laser spot, high energy density and fast cutting speed. The laser beam focuses on a small point of light, which makes the focal point reach a high power density. At this point, the heat input of the beam is far more than the part of the material reflected, transmitted or diffused.

DIP - Quick Guide - tutorialspoint

Lets take the point r to be 256, and the point p to be 127. Consider this image to be a one bpp image. That means we have only two levels of intensities that are 0 and 1. So in this case the transformation shown by the graph can be explained as. All the pixel intensity values that are below 127 (point p) are 0 , means black.

Because of the high degree of beam collimation, a laser serves as an almost ideal point source of intense light. A laser beam of sufficient power can theoretically produce retinal intensities at magnitudes that are greater than conventional light sources, and even larger than those produced when directly viewing the sun.
