Evolution ensures that our eyes are fully adapted to sunlight. This
contains more green areas, so our visual organs are more sensitive to
green, which is why the green grass standing on the viewing platform is
easier to attract the eye than the brown-blue water in the same
environment. The light of the green laser pointer is easier to recognize
than the blue one. Therefore, the blue laser pointer must emit much
brighter light than similar Rechargeable Laser Pointer, which is why in the case of poor quality, the upper limit... more

Laser quenching is a surface hardening process. It can only be used
to cure iron-based materials. That is, steel and cast iron with a carbon
content of more than 0.2%. In most cases, the laser beam heats the
metal surface to near its melting point (900-1400 C) to solidify the
workpiece. Even if it is 8 times, it may not be a problem, but if you
compare the same 1mw, for example, the difference is obvious. There are
more than 2W. Generally sold laser pointers are below 1mW, so the output
is as high as 2000 times. Moreover,... more

What is the Tyndall effect?
If the laser is not directed at you in a vacuum, you will not be able
to see it. However, the air we breathe together is not a vacuum. Among
them are dust, suspended particles and so on. The bright "passage" of
the laser light is formed by the scattering of light by these particles.
We call it the "Dyndall Effect". Light is w... more
