Why do dogs madly chase laser pointers
Unlike the laser pointer made by direct diode, the laser conversion efficiency of the 532nm green laser pointer is not 100%. All green laser pointers should be added to the laser beam filter to prevent 1064nm IR laser. The actual output power of the green laser pointer should be the power of the 532nm green laser. Sometimes, the DPSS high power laser pointer provided by the laser supplier has a mixed output power of 532nm and 1064nm instead of a separate 532nm laser power. In fact, the 532nm green laser pointer without infrared filter does not reach the actual output power it should. It is understood that the laser can be converged into a very tight beam, then tuned to a single frequency, and then penetrate the dust and gas in space. At the same time, any lasers that eventually reach the earth may be very short, because they are not sent to the earth, but only sent to the earth in a short time. The same is true for radio, but the difference is that people are more concerned about the purple laser pointer in the spatial scanning area than radio. Ultraviolet lasers are the best choice for various PCB applications in various industrial applications, from the most basic circuit boards and circuit wiring to the production of pocket embedded chips and other common advanced processes. This material difference makes UV lasers the best choice for various PCB applications in a wide range of industrial applications, from the production of the most basic circuit boards and circuit wiring to the production of compact embedded chips and other advanced processes.

The most powerful laser cutting can not only eliminate the influence of mechanical stress, deformation and damage to circuit components during the disassembly process, but also has less thermal stress than other lasers such as CO2 laser cutting. The reduction of cutting pads can save space, which means that components can be placed closer to the edge of the circuit, and more circuits can be installed on each circuit board, which maximizes efficiency and meets the needs of flexible circuit applications. The working principle of the accelerator is to project a high-energy, high-brightness blue laser pointer beam onto a thin metal foil target with an area of only a few square microns. "The energy of the green laser pointer pulse is very large, and the energy of the electromagnetic field produced is even an order of magnitude larger than the Coulomb force inside the atom," Hidding explained. "Therefore, the metal foil target will be converted into plasma immediately." Plasma particles are strongly excited by laser and other plasma fields. The degree of acceleration depends on the initial position of the particles. This process can generate huge amounts of energy.
