Class A pocket mini laser pointer, low power consumption and long life. The brass shell can effectively deal with various external impacts. Pocket laser pointer, beautiful and generous. 1 dry battery design, easy to replace; pen body design pen holder, pocket Laser pointer is more convenient to carry. The quality is reliable, and it can be applied to various large-scale auditoriums, conference venues or outdoor adventures and other environments.
The red-light pocket laser pointer has the simplest structure. The reason why it is simple is that the red-light laser pointer is basically just a diode with a battery as the energy source. And there are laser diodes that generate this wavelength. The red pocket laser pointer first appeared in the 1980s. It is a large and heavy device worth hundreds of dollars; it is very small and very cheap. A yellow pocket laser pointer with a wavelength of 593.5nm appeared on the market. Based on DPSS technology, two laser beams with wavelengths of 1064nm and 1342nm are added through a nonlinear crystal. The complexity of the process makes the yellow pocket laser pointer unstable and low efficiency. The output power of the pocket laser pointer is 1-10mW with temperature changes. If it is overheated or overcooled, the mode will jump. This is because the size of the laser pointer does not provide the required temperature stabilization and cooling components.
