The last problem with laser pointers is the biggest problem, which is safety, which is due to the ever-increasing power output available today.

Usually, the power of laser pointers is limited to 5 milliwatts, but some manufacturers seem to cater to customers who want more power. They provide pointers that are more like flashlights and output up to 500 milliwatts in green or red laser. Rocket scientists also do not need to purchase original laser diodes and drivers to create laser diodes that are higher than legal laser pointers.
