Scientists create sharpest laser pointer
In theory, lasers have only one color, frequency or wavelength. In practice, however, there is always a certain line width. Researchers, including those at the German Federal Physicotechnik AG (PTB), have now developed a laser with a linewidth of just 10 millihertz (mHz) - closer to the ideal red laser pointer than ever before.
Red laser pointers are less expensive to produce and are therefore generally less expensive than high power laser pointer. Red lasers are said to have longer battery life and lower operating costs. This precision can be used in a variety of applications, such as optical atomic clocks, precision spectroscopy, radio astronomy, and testing relativity. More than 50 years have passed since the laser was first technically realized, and we cannot imagine how we would live without it today. But currently green lasers are rapidly gaining popularity.

200mW Laser Pointer: The Cheapest Form of Lighting
In fact, people have been fascinated by 5mw laser pointer technology since its invention, long before it. They are the inspiration for countless science fiction, comics, movies, and TV shows, and their properties are often exaggerated, but over time, most of them actually turn out to be true. Red lasers are currently produced on a larger scale, which means they are readily available on the market.
A 1mw green laser pointer might not be enough, and a red one might not be enough. Where do you want the 12V from? I prefer cheaper versions or green laser pointer that don't flatten out in the darker months, but this film works for other uses as well. Hit it with a laser pointer!
