Unusual 532nm laser pointer
Some guns use a laser beam that shows exactly where the bullet is in the target object. Lasers more heavy machinery can use lasers as weapons to create powerful and destructive armor. Another problem with using crystals in 532nm green lasers is that not all 808nm infrared laser power is converted to green light. Therefore, using a normal 532nm green laser pointer also emits a lot of infrared light, which is bad for the eyes. Some laser pen companies advertise the use of infrared filters to block unwanted infrared radiation, but this usually equates to greater power loss and lower efficiency. Therefore, most 532nm laser Pointers are not equipped with infrared filters. How many electric fingers should the amateur astronomer choose to refer to the stars in order to meet the demand? Personally, I think the power of 200mW to 500mW is more appropriate, and the power of 500mW or more can feel the special sunshine in the room.

Laser pen 1200mW laser price main and secondary bandwidth bandwidth stability, the price is more expensive, but the human eye can not distinguish the difference between this bandwidth, which in the economy bundled friends choose the most 200 milliwatts of power, laser pen price of several hundred dollars more appropriate. In addition, the general high powered laser pen power consumption is larger, but also the need for environmental protection and cost saving principles, equipped with a good rechargeable battery. At present, 50000mW laser electricity price is not expensive, only more than 10000mW laser.In recent years, Europe, and the UK in particular, have taken an increasingly strict stance on logistics guidelines. In most European countries, the power limit for selling laser Pointers has been reduced from 5 mW to 2 mW. In the UK, this has been greatly reduced to 1 megawatt. This suggests they are trying to limit the use of laser Pointers to the classroom -- laser Pointers for demonstrations -- and nowhere else.
