What is the best high precision laser pointer?

For a long time, laser power measurement has been the main content in research, medical and manufacturing applications. But now, laser power measurement equipment is being incorporated into automobile manufacturing more than ever. For a long time, the automotive industry has been known for its reliance on precision, precision and process quality. Today's cars must be manufactured in accordance with very strict safety standards and regulations. Minor manufacturing errors on the assembly line can have devastating consequences in the real world. When helicopters perform search and rescue missions, they are at the mercy of the wilderness and wind and rain, hoping that the people they are looking for can signal and be seen in some way. One way is to use smoke signals. A simpler and safer method is to use a high-power visible green laser to aim the beam. Not only can this be seen from miles away, but it can also be a successful search and rescue mission.
