The flash disk green laser pointer has the function of flash disk

The CO2 molecule laser transition energy level diagram. CO2 laser excitation conditions: the discharge tube, usually enter the tens of mA or hundreds of mA DC current. Discharge, the nitrogen molecules in the gas mixture in the discharge tube due to electron impact has been aroused. When molecules are excited nitrogen and the CO2 molecule collision, the N2 molecules of the energy transfer to the CO2 molecule, the CO2 molecules from the low-energy level transition on the energy level inversion issued by the laser. Structure: (1) laser tube: is the most critical components of the laser machine. Commonly used in hard glass, general layer telescopic structure.   green laser pointer   will make it more convenient for the customer to use the laser pointer in the practical use.
The innermost layer is the discharge tube, Layer 2 water-cooled casing, the outermost layer of the gas tube. The carbon dioxide laser discharge tube diameter than the He-Ne laser tube thick. Thickness of the discharge tube are generally no effect on the output power, spot size caused by diffraction effects are taken into consideration, should be based on the length of the tube. The length of the tube a little rough, tube short fine point. Discharge tube length is proportional to the output power. A certain length, per meter discharge tube length of the output power increases with the total length of Plus water-cooled cooling the working gas, the output power stability. Discharge tube at both ends and the gas pipe connection, namely, the gas pipe with a hole at one end connected with the discharge tube. The flash disk  green laser pointer  has the function of flash disk.
The other end through a spiral back to the trachea and the discharge tube connected, so you can make the circular flow gas discharge tube and gas tube, gas discharge tube is ready to exchange. CO2 laser structure. Optical resonator: CO2 laser resonator commonly used concave cavity mirror K8 optical glass or optical quartz processing of National Cheng Kung radius of curvature concave mirror, the mirror coated with highly reflective metal film - gold-plated membrane wavelength of 10.6μm at the reflection rate of 98.8%, and chemically stable. Carbon dioxide emitted light to infrared light. Therefore, the mirror needs to be applied through infrared optical materials, because the ordinary optical glass for infrared light through. Requires to open a small hole in the center of the reflecting mirror. So that the customer can use this kind of  usa green laser pointer     to store the data.
Resealing a through 10.6μm laser infrared materials to a closed gas. This part of the resonant cavity laser to form a laser from holes output cavity. Power and pump: a closed CO2 laser discharge current is small, cold electrode, cylindrical cathode made of molybdenum or nickel plate. 30 ~ 40mA operating current, the area of the cathode cylinder 500cm2, not the lens contamination, plus a light bar between the cathode and the lens. Pumped using a continuous DC power to stimulate. Motivate the principle of the CO2 laser DC power DC voltage AC voltage in the city transformer to enhance access to high-voltage and high-voltage rectifier and high-pressure filter in the laser tube. And at the same time the laser function of    green laser pointer    can be applied.
The lasers most of the incentive system, the laser material and optical resonator composed of three parts. The incentive system is to produce solar energy, electrical energy or chemical device. Incentives currently in use, light, electricity, or chemical reactions. The laser material is able to generate the laser material, such as ruby, beryllium, glass, neon, semiconductor, organic dyes and so on. The role of the optical resonator be used to enhance the brightness of the output laser, regulation and the selected wavelength and direction of the laser. Standard for technical reasons: laser laser marking technology in recent years more and more applications in the field of printing, laser marking can be applied to a variety of materials including plastics and rubber, metal, and silicon wafers. The 3 in 1   green laser pointer    is also very popular.
