The engineer is making the drawing of green laser pointer on the computer

YAG crystals containing neodymium (ND) laser wavelength of a human eye can not see for the near infrared light 1.064um. This beam can be achieved in the weak excitation case, the continuous oscillation. YAG crystal is the abbreviation of the gem yttrium aluminum garnet, with excellent optical properties, is the best laser hair oscillator crystal. Zi light the main specialty. Monochrome - The laser is not a variety of light mixed together made it the most pure monochromatic light (He has the length, frequency). Directional - light olive propagation basically does not spread out. Relative to one thousand - the emblem of the light phase (peaks and troughs) is very laws of coherence. The warehouse is checking the quantity of parts of china laser pointer.
The high output power of a lens focusing the laser, the resulting energy density of sunlight hundreds of times. Laser welding using a laser beam of excellent directivity and high power Mody density characteristics of the work. The laser beam is focused through the optical system in a small area, welded at the formation of an energy highly concentrated heat source area within a very short time, so that the solder material melts and forms a solid solder joint and the weld. Commonly used in laser welding of two kinds: the pulsed laser welding and continuous laser welding. The former is mainly used for single-point fixed continuous and thin material welding. The latter is mainly used for welding and cutting large pieces of thick. The surface treatment of china laser pointer plays a decisive role in the manufacture.
Laser welding characteristics of the processing methods. Non-contact processing, without pressure on the workpiece and the surface treatment. Solder joints, high energy density, suitable for high speed machining. Welding a short period of time, both on the outside and the heat-affected, but also the thermal deformation and heat affected zone is small, and is particularly suitable for processing high melting point, high hardness, specialty materials. Do not need to fill the metal, does not require a vacuum environment (in the air), not like the electron beam in the air as the danger of X-ray. Compared with exposure to welding process. Electrodes, tools and other wear and tear. Processing noise pollution to the environment. Small parts can be processed. In addition, the welding can also be carried out through the transparent material of the wall. The manager and the customer are negotiating the price of china laser pointer.
Through the optical fiber to achieve long-distance, hard to reach parts of the ordinary method, multi-channel or time welding. Very easy to change the focal length of the laser spot position. Very easily equipped with automatic machines, robotic devices. Conductor with the insulating layer can be directly welded large performance difference between the dissimilar metals can be welded. Pulsed laser welding mechanism. Pulsed laser welding can be divided into heat and melt welding and deep penetration of the fusion welding of heat and melt welding is when a laser beam to the surface of the material, the material to absorb solar energy heating and melting. The surface layer heat conduction to continue to pass material depths, until the two contact surfaces to be welded miscible and welded together. The engineer is making the drawing of green laser pointer on the computer.
Deep-penetration melting welding is a higher power density laser beam to the material, the material is processed melt as well as gasification, resulting in a larger vapor pressure, in the role of the steam pressure, the melted metal is pushed around radiation at the (bath) showing a pit, and continue with the laser beam irradiation, the pit is deeper, and penetrate to another workpiece. Laser to stop after irradiation, the melted metal being excluded from the pits around the re-flow back to the pits where freezing after the workpiece welding together the two laser welding mechanism, with the power density, exposure time, material properties, welding, etc. factors. The dispatcher added 2 more workers to the night shift of    china laser pointer.
