There is controversy about the inventor of the powerful blue laser pointer. Charles H. Towns is considered the inventor of the first laser. Some people think that the laser pointer was invented by one person or a team, while others disagree. Some people think that the invention of the laser pointer crow is not personal, but the result of cooperation, because there are still many patents in the process of laser development. Despite the controversy, laser technology has rapidly spread and developed in recent years. Anyone who develops new forms of lasers or discovers new applications is highly valued. The laser amplifies the light source and converts it into a powerful light. The laser pointer power supply must be powered by batteries, power supplies, or other power sources (such as lasers). The laser pointer also needs a medium that can amplify light. When the laser is energized and the laser medium is present, a focused beam is produced. The beam will then be emitted to the outside as a straight and bright beam. The term "laser pointer" is an acronym for the term "stimulated emission optical amplification".
