532nm green light from a green laser pointer
The beams from these high power laser pointer are too weak to be easily blocked by fog, smoke and ambient light. High power laser pointer beams can be easily displayed at night in the harshest conditions, and higher power modes can be seen throughout the day. There are regular 405nm blue-violet lasers, 650nm and 635nm red lasers, but green laser pointers are the only option for amateurs and astronomy professionals because the green laser beam is the most prominent. Green laser pointers represent high coherence, high directivity and high brightness, with excellent collimation and alignment advantages. The green laser pointer can emit the most sensitive 532nm green light, and the human eye can achieve the best effect in the long-distance focusing operation. Great for sunrise and sunset astronomy. For astronomy enthusiasts, lasers above 50 mW are suitable for observing stars and other celestial objects. As laser pointers developed throughout the astronomical field, experts invented special astronomical lasers. A very important use of laser pointers in caving is to determine the presence and depth of passages and pits. For example, by scanning the walls and ceilings of large cave rooms, you can spot openings and passages in the distance and examine them with a laser beam.

Another use of lasers in cave exploration is to examine underground pools and streams. If the water in the cave is relatively clear, a laser pointer can be recommended to illuminate the underwater terrain so that people on the water can see it. Most people generally wish to use a telescope for professional astronomical research. However, astronomers are limited by position, angle and distance in stargazing and observing celestial objects. It's always annoying when people are constrained by the faint light from the telescope during the search. The black color is very convenient for the operator to pop the balloon well because it can easily absorb enough energy in a short period of time. When the green laser pointer is pointed at the black balloon, the balloon immediately absorbs enough heat and starts popping for only a few seconds. This method is not as effective as putting strong light into the water, but it can be done from a distance without entering or contaminating the water. The special emission of the 635nm red laser beam will bring a completely different experience when directing such a red laser in the dark. 1mW series red laser pointers project the purest red light in every situation. This low-power red laser pointer is not as sensitive as the human eye's green laser, and is good enough to display stars, constellations, astronomical research, bird discovery, school education, exhibitions, and more. No one will regret owning this 1mW red laser pointer on any display occasion.
