the receiver of laser pointer

Laser welding can be successfully used to achieve wire connection with lumped elements, block elements can be any size. Should be noted that in welding filamentous component geometry. Different metal welding. Different types of metal welded to solve weldability and solderability parameter range. Laser welding between different materials, only certain combinations of materials possible. Laser brazing. Some components of the connection should not be used laser welding, but can use the laser as a heat source, the implementation of soldering and brazing, laser welding also has the advantage. Brazing using a variety of ways in which the laser is mainly used for soldering printed circuit board soldering, especially useful in chip component assembly. Users need not to align the emitter with the receiver of laser pointer  with remote control.
Laser soldering compared with other methods has the following advantages: because it is local heating element is not easy to produce thermal damage and heat affected zone is small, it can be implemented in the vicinity of the thermal component soldering. Non-contact heating, melting bandwidth, does not require any auxiliary tool in the double-sided printed circuit board components and equipment after the processing. Repeat stability. Flux for welding tools pollution, and the irradiation time and easy to control the output power, laser soldering yield. Splitting the laser beam is easy to implement, can be used semi-lenses, mirrors, prisms, mirrors and other optical components scan time and space partitioning, to achieve more symmetrical while welding. Multi-wavelength laser brazing 1.06um laser as a heat source, available optical fiber transmission, it can be difficult in the conventional way of processing parts of welded, good flexibility. Focus is good, easy to implement automated multi-station devices. Laser deep penetration. Metallurgical process and process theory. Physical metallurgy of laser deep penetration electron beam welding process is very similar, namely, the energy conversion mechanism is through the "hole" structure to be completed. The rubber also can be the body material of laser pointer .
At sufficiently high power density beam irradiation, the materials have evaporated to form holes. This is full of holes like a blackbody of steam, almost all the energy absorption of incident light, the hole cavity equilibrium temperature of 25,000 degrees. From this high-temperature heat transfer out of the hole wall cavity, so that the hole surrounded by metal melting chamber.
