What is a visible laser?
The visible laser is a laser with a beam that can be seen with the naked eye. Visible lasers are somewhat rare; Most lasers emit light in an invisible infrared spectrum. Lasers, which are usually invisible, can be visible with smoke or dust, but there are some types of lasers that produce rays that are truly visible to the naked eye and even pass through clean air. There are several different types of visible lasers such as laser diodes and gas lasers.
The term laser is actually an abbreviation for "light amplification by stimulated emissions". Through the process known as stimulated emissions, lasers release light or electromagnetic radiation. Electronically, the electron is stimulated and moves to the lower energy area. The lost energy takes the form of photon, units of electromagnetic radiation and is emitted in the form of laser beam. In a visible laser, the light is emitted on the wavelength that is in the visibleThe spectrum, unlike most lasers that release energy in an invisible infrared spectrum. The laser diode, which is similar to a simple light emitting light or ice, rarely releases a visible laser. However, several laser diodes can release visible rays. Some lasers that operate with exciting electrons in different substances such as titanium or nitride Gallia are also able to release visible rays.
Gas lasers are often used to produce visible laser beams. In the gas laser, the electric current is sent by gas that stimulates electrons in gas atoms to drop lower energy levels and produce photons or light. The first laser was made of helium and neon gases. Helium-neon lasers, also referred to as hene lasers, produce visible laser beams in the red area of visible spectra.
as well as the invisible lasers and chasOne hundred can cause visible lasers to damage the eyes. Within a few seconds or less, the laser can cause small, located and permanent burns on the cornea or lens of the eye. This applies even if the beam binds the contact with the eye after the reflection from the reflective surface. Some scientific and industrial lasers are even strong enough to burn the skin, and even traces of light scattered from such lasers can cause permanent eye damage. Due to this risk, special safety glasses can be used to protect the eye to absorb the light of specific wavelengths.
