What does mw mean laser pointer?

The term "mW" stands for milliwatts, a unit of power commonly used to describe the output of laser pointers. The higher the mW rating, the more powerful the laser, which typically translates to a brighter beam and increased visibility. For instance, a 5 mW laser pointer is often used for presentations, while those with higher ratings may be used for more specialized purposes, such as astronomy or professional applications. However, safety standards should always be considered, as higher-powered lasers can pose risks to eyesight.
