Laser marking machine frequently asked Questions?

Ans: Laser marking machine -  In common language laser machines are an unusual source of coherent, monochromatic light beams.
A laser is one of the biggest technical achievements of 20th century that produces a very narrow beam of light that is useful in many technologies and instruments. The letters in the word laser stand for Light Amplification by Stimulated Emission of Radiation.
The laser light waves travel together with their peaks all lined up, or in one phase which is why laser beams are very narrow, very bright, and can be focused into a very tiny spot. When pointed at something, the energy of the narrow beam of extremely directional light, having high intensity stays focussed at a tiny spot producing accurate, precise and sharp marks on the product of any shape, size and material.
 The three basic components of a laser marker are:
Lasing material (crystal, gas, semiconductor, dye, etc...) or a laser medium
Energy or Pump source
Optical cavity consisting of optical resonators to act as the feedback
 Types of laser markers:
Laser markers are often described by the kind of lasing medium they use
Solid state marking lasers have lasing material distributed in a solid matrix, e.g., the ruby or neodymium-YAG (yttrium aluminium garnet) lasers. The neodymium-YAG laser emits infra-red light at 1.064 micrometers.
Gas lasers -helium and helium-neon, HeNe, are the most common gas lasers and are used for cutting hard materials.
Excimer lasers.
Dye lasers use complex organic dyes like rhodamine 6G in liquid solution or suspension as lasing media. They are tunable over a broad range of wavelengths.
Semiconductor lasers, sometimes called diode lasers, are not solid-state lasers. These electronic devices are generally very small and use low power.
 Time modes of operations of laser machines
Continuous Wave (CW)
Single Pulsed (normal mode)
Single Pulsed Q-Switched
Repetitively Pulsed or scanning lasers
Mode Locked lasers
