Various laser pointers on the market

A low power 5mW green laser pointer (Class IIIa) is the safest laser to use. Satisfy basic demonstration applications such as laboratory experience, astronomy, reading, and education. But at the same time, as the application advantages increase, the price of blue lasers also becomes higher than other lasers. In fact, it is very difficult for ordinary people to pay. The base price of these lasers is $700 compared to the measured price of $60 to $100 for red lasers. So you can see these are not easy to have. You need to have a budget and a clear purpose for purchasing these lasers. The reason their prices vary so much is the technology behind them.

Astronomy enthusiasts and professionals, because the green laser beam is the most visible one. Features with high coherence, high directivity, high brightness, and pointers are usually 405nm blue-violet lasers, 650nm and 635nm red lasers, and 532nm green lasers, but 532nm green laser pointers are the only choice for astronomy enthusiasts and professionals, because green high power laser pointer beams are the most obvious of them all.
