The power of green laser pointer fluctuates at 50mW

 The power of green laser pointer fluctuates at 50mW.
Due to its unique characteristics, especially suitable for use in the sensor seal welding, many foreign manufacturers of the production sensors use laser welding process to produce sensor, while the domestic use of the small manufacturers of this technology, mainly the production of military sensor products manufacturers and some research institutions in the use of such technology, and the use of foreign laser welding machine more. Domestic laser welding machine performance and foreign products, not far off, fully capable of the domestic production process requirements of the sensor, but the price is 1/3-1/5 of the similar foreign products. In order to improve the overall level of domestic sensors and the development of national laser industry. If the power of green laser pointer is fixed. 
Precision laser processing technology to the sheet (0.1 to 1.0 mm) as the main processing, machining accuracy is generally in the 10 micron; laser micromachining technology as the main processing for a variety of film thickness below 100μm, Its precision is generally less than ten microns or even sub-micron level. It must be noted that, in the machinery industry, precision usually refers to the surface roughness is small, a variety of tolerance (including the location, shape, size, etc.) range. Laser precision machining is a non-contact processing, there is no mechanical force. If the power of green laser pointer is focusable.
EDM, plasma arc processing, the heat affected zone and the deformation is small, and thus able to process very small parts. In summary, laser precision machining technology has many advantages than the traditional processing methods, and its very broad application prospects. Introduction of the commonly used laser precision machining equipment. Generally used for precision machining lasers: CO2 lasers, YAG lasers, copper vapor lasers, excimer laser and CO laser, its laser characteristics detailed in literature [6,8,12-16]. High-power CO2 lasers and high-power YAG lasers in the large-scale laser processing technology to a wider application; copper vapor lasers and excimer lasers in laser micromachining technology, used more often. Or the power of green laser pointer can be focused by rotating the laser head.
