Field rescue-laser pointer plays a major role
532nm green laser pointer can provide enough distance
The 532nm green high powered laser pointer will be the brightest color in the human eye, so it is the largest for this type of application under the same output power. But this does not mean that blue, red or violet lasers cannot be used. Any laser whose power is high enough to be visible at night will be beneficial over long distances. The most important thing is, yes, even greater than the wavelength of the nanobeam is the intensity of the laser. You can use the green laser pointer of 532nm (the brightest color in the visible spectrum of the human eye), but if it is less than 5mW, you will not be able to obtain the visible range of a higher power unit.

Green laser pointer is small and portable, convenient for field rescue
It is very important to ensure safety while enjoying outdoor activities. Not only to teach your children and any young hikers, but also for the safety of yourself and your team. It is easier than many people think to leave the trail and find the way back. Think about whether the woman in Hawaii who was relatively unharmed after 17 days in the wilderness had a 100mW green laser. She could have sent her position from the forest floor to the mountain peak, to the drone and helicopter that she could see from above. Fortunately, she was found and is still alive, but this situation does not always end in a happy ending.
