Where is the high quality laser light reflected?
Depending on the situation, high-quality laser pointers will be better than others. When you need to point out the constellations, please buy a powerful laser pointer that can clearly point to a point in the sky. If your application requires a specific range or extended distance, please be sure to contact us to help determine the best Laser pointer for your application. We can assist in selecting a laser that meets your application requirements to meet your requirements for distance, visibility, output power and beam intensity for any desired target.

Laser light source for high-resolution near-field optical applications with output power exceeding 1 mW (times of 104 power) and small (300 nm square to less than 50 nm square) output beam size. Ultra-small aperture lasers (VSAL) have greatly expanded the range of possible applications of near-field optics and improved the signal-to-noise ratio and data rate obtained in existing applications. For example, a 250-nanometer diameter mark corresponds to 7.5 Gb/in. 2 The storage density has been recorded and read back the phase change in rewritable reflection and transmission. The disk speed is 24 Mb/s, 250 nm square aperture VSAL. Laser machining is quite popular as a technology for fast processing. This was because lasers can melt and evaporate the work piece efficiently as being so directional and light-harvesting as to concentrate energy in a micro area, resulting in an increase in processing speed. On the other hand,in some cases, the high energy density prevents a sufficient rocessing quality from being obtained.This is because the irradiated laser's excessive heat input into the processing object causes an affected layer in the processed area under the influence of heat, and such a heat-affected layer prevents the specifications required for the work piece, including material strength, from being satisfied. In the laser processing field.
