The principle of laser generationLASER is written as "Light Amplification by Stimulated Emission of Radiation", which means that by the principle of "excitation emission", the amplification of light waves is generated, which is called "laser". The motion state of electrons can be divided into different energy levels. When electrons transition from high energy level to low energy level, they will release electromagnetic waves of corresponding energy (the so-called spontaneous radiation).

Mode of operation of laserThe laser with different wavelength and different output mode will be absorbed by different tissues or substances after entering the skin and thus produce different action modes. These tissues or substances are called Chromophore.Photothermal action refers to the absorption of laser light into the skin by specific pigment groups and then converted into heat energy. Depending on the duration of the laser pulse and the heat dissipation time of the skin tissue, the heat may spread to the surrounding tissues and cause a wide range of heating (e.g.

Optical terms for cosmetic instrumentsA photon is an elementary particle, a quantum of electromagnetic radiation. In quantum field theory, it's the force carrier that transmits the electromagnetic force.Light spots/spots are few and far betweenLight spot is the contact point of light contact skin, different instruments have different light output size and shape. Such as color light instrument contact point is generally rectangular, size marked as long x wide (for example: 10mm x 25mm). Generally, the laser output is a dot, and the size is marked as the diameter (e.g., 3mm, 8mm, etc.).

Precautions for using laser and colored light◇ In the course of optical treatment, the operator should minimize the potential risks to the person present and the possible side effects to the customer◇ During the course of treatment, unauthorized persons are forbidden to enterAll reflective materials and inflammable materials should not be placed in the treatment room, such as mirrors and reflective glass objectsCarbon dioxide extinguisher should be placed in the room◇ Beauty care center should keep the fire outlet unblockedDoors should be kept closed and Windows should be covered with light -

How to prolong the service life of laser tube1 laser engraving machine, cutting machine in the use of laser tube, need to pay attention to the best use of pure cooling water, and keep the water temperature below 25℃.2. Summer temperature is high, it is necessary to pay attention to frequently change the cooling water, found that the temperature is too high, need to stop and rest and replace the cooling water; Winter temperature is low, the machine after the completion of the work, need to put the laser tube internal cooling water, to avoid the laser tube is frozen cracked.3.

A key query is how to make sure "fast enough", that is, what elements affect switching off the tube rapidly to keep away from the penalties of inductance saturation? This may also be the last determinant of the quantity and charge of the inductor, so it is vital to have a exact appreciation of the response time issue.1. All present day limiting loops require a positive time response.

Influencing factors of inductance saturationA key question is how to ensure "fast enough", that is, what factors influence switching off the tube quickly to avoid the consequences of inductance saturation? This may be the ultimate determinant of the volume and price of the inductor, so it is important to have a good understanding of the response time issue.1. All current limiting loops require a certain time response.

Why the laser is weak or has no laser outputWhether the focusing mirror is contaminated: Clean the focusing mirror.Whether the focal length of relief engraving machine equipment changes: readjust the focal length.Whether the optical path is offset: Adjust the optical path carefully.Whether the reflector is contaminated or damaged: Clean or replace the reflector.Whether the laser power supply is powered on: Check the power supply loop of the laser power supply to make it normal.Whether the laser tube is damaged or aged: Replace the laser tube.Whether the laser power supply is damaged: Replace t

Carbon dioxide laser is a gas laser with CO2 gas as the main working substance (CO2: N2: He=1:7:20). The CO2 laser consists of a discharge tube, a resonator and an electrode. With the addition of a DC high voltage pump, the gas in the discharge tube emits light (the output wavelength is 10.6μm).
