Since the invention of laser, with its excellent properties, in industrial processes, medical hairdressing, scientific research and other fields obtained the extremely widespread application.
Laser has four main features, respectively, high brightness, good directivity, good monochromaticity, high coherence.
These features associated with each other, making the laser can be applied to different scenarios.
if you are looking for laser equipment, you can contact us. 4000 - 818 - 380
the laser energy
are highly gathered, mainly due to its beams of light. High brightness characteristics of laser, and it is the energy highly centralized embodiment. Near the focus after lens focus, can form the thousands of degrees, even tens of thousands of degrees high temperatures, this feature makes it almost all of the materials can be processed.
the height of the energy concentration is one of the characteristics of the laser is very important, it is for this advantage, make it can be widely used in industrial processing, and medical and other fields.
monochromaticity
the color of the light is determined by the wavelength of light, and light will have a certain wavelength range. The wavelength range is narrow, the better monochromaticity will be displayed. For ordinary light source, because the line width is bigger, too wide frequency range, color will be more noise.
although, compared with ordinary light, laser linewidth is much narrower. However, laser linewidth restricted by many factors, it is almost impossible to achieve the theoretical level. For example, the change of the temperature, the shake of the laser, the optical device airflow volume, as well as the external factors such as pump leads to the resonance frequency is not stable, leads to lower performance.
directional well
from the light source of light is propagated along each direction, the divergent Angle is very large. By comparison, laser divergence Angle is very small, almost along the direction parallel to the launch. Laser emission of light is a kind of polarized light, the direction is fixed. A simple case intuitively describe this: laser refraction as water will not occur.
in various kinds of laser, gas laser on the directional performance most prominent, the second is that solid state laser, semiconductor laser is less in this regard.
good coherence
light is composed of a myriad of light quantum, the light emitted from the laser quantum due to the resonance principle, on the wavelength, frequency, polarization direction are consistent, which makes it has very strong ability to meddle. We will also usually laser is called coherent light. Because compared with ordinary light, laser better coherence.
