Place Anywhere On The Table Green Laser Pointer
In terms of security, the research team also preset multiple barriers. A green laser pointer emitter surrounded by four protective light beams and a photodiode. The sensor cuts off the circuit when it senses someone approaching. One of the reflectors (which sends the protective beam back) prevents someone from getting burned while crossing the laser beam. To reduce the excess heat from energy transfer, the researchers used aluminum bars to dissipate heat. Of course, not all heat is wasted because small thermal motors capture energy and transfer it to the cell phone battery. The research team said that the future iterative system is expected to increase the transmission area to 100 square centimeters and the distance to 12 meters. Ability to charge devices where the green laser pointer is placed anywhere on the table.

Analysis of the development status of China's semiconductor laser industry. Semiconductor green laser pointer has a bright future. The semiconductor laser has the characteristics of good directivity, high brightness, good monochromaticity, and high energy density. The semiconductor laser industry based on semiconductor lasers has been developing rapidly in the world, and has now been widely used in industrial production, communications, information processing, medical and health, military, cultural education and scientific research. Because semiconductor lasers have many advantages. In order to occupy the commanding heights of green laser pointers in the global competitive environment in the developed countries.
Therefore, it depends on the situation, whether it is a classroom, home, office or laboratory. Key switches may be essential, but for most everyday users, they seem too large.
