The blue ray laser pointer pen must be very expensive

Currently, the accepted principles are two: "thermal processing" has a high energy density laser beam (which is the focus of the energy flow), irradiation in the surface to be machined on the surface absorb the laser energy, heat generated in the irradiated area excitation process, so that the material surface (or coating) temperature rise, resulting in abnormal, melting, ablation, evaporation and other phenomena. "Cold" load high energy (UV) photons, can interrupt the material (especially organic material) or the chemical bonds within the surrounding medium, to the occurrence of non-thermal process the material damage. The blue ray   green laser pointer    must be very expensive.
This cold processing laser tag has a special significance, because it is not thermal ablation, but do not have a "thermal damage" side effects, break chemical bonds of the cold strip, and thus be processed in the surface layer and in the vicinity do not produce heat or thermal deformation and so on. For example, the electronics industry in the use of excimer laser deposition of chemicals on the substrate film on the semiconductor substrate out of the narrow slot. CO2 laser printer standard machine-ray machines can be carved a variety of non-metallic materials. Used in garment accessories, pharmaceutical packaging, building ceramics, beverage packaging, fabric cutting, rubber, shell plate, gifts, electronics, leather and other industries. The yellow ray   100mW green laser pointer   is much more expensive compared with other kinds of    laser pointer pen    .
A typical application cases, such as packaging of the box flight laser marking, paper, metal detonator shell code printing. Check the water, can only start after the circuit is correct. Boot sequence is: connect the power line, turn the key switch. At this point the machine is powered ventilation and refrigeration systems, ammeter shows the value of about 7A; wait 5 to 10 seconds, press the trigger button on the outside of the control panel, ammeter shows a value of zero, 3 to 5 seconds, the krypton lamp lit, ammeter shows value 7A. (Refer to the laser power operating instructions); open scanner power; turn on your computer, transfer the required marking documents; adjusting the laser power to the operating current (10 ~ 18A), you can start marking. The appearance of  50mW blue violet laser pointer     is closely related to the development of the materials.
Carbon dioxide laser, can be called "stealth" because it sends a laser wavelength of 10.6 microns, "body" at the infrared region, the naked eye can not perceive that it works with continuous, pulsed two. Continuous-generated laser power up to 20 kilowatts or more. Pulse-generated laser wavelength of 10.6 microns is the most powerful kind of laser. People have been using it to "fight" out of the neutron in the nucleus. The emergence of carbon dioxide lasers is significant progress in the development of laser, light weapons and nuclear fusion research is the significant results. The most common carbon dioxide laser is a discharge of about 1 meter long. It is produced by the laser is invisible, in the brick on brick enough to burn a dazzling white light. If the relevant materials haven’t been exploited yet, there will be no chance for we to see some new types of    laser pointer pen    .
Carbon dioxide laser is a CO2 gas as the working substance of gas lasers. Discharge tube is usually made of glass or quartz material, which filled with CO2 gas and other auxiliary gases (mainly helium and nitrogen, usually a small amount of hydrogen or xenon); nickel electrode is generally hollow cylinder; cavity one end is gold-plated reflecting mirror, the other side is part of germanium or gallium arsenide polished mirror. When the high voltage electrode (usually a DC or low frequency AC), the discharge in the glow discharge, germanium laser output mirror at one end there is, its wavelength of 10.6 microns in the near infrared; generally good tube .   200mW green Laser Pointer    is the red laser pen.
