The sale of the product in Germany is prohibited if the hazard cannot be excluded. This applies to all the strongest laser pointers above 1mW, i.e. class 3 to 4. Therefore, only laser markings of class 1 to 2M can be traded in Germany. Laser shows are used in various occasions. The classic application in nightclubs is no longer the only one: laser shows (in combination with multimedia shows) are almost standard on cruise ships, and many amusement parks have demonstrated the application of laser shows in various aspects. But laser shows are also used time and time again for product demonstrations by major automakers. Of course, laser shows at urban festivals and anniversaries are gaining popularity as a real alternative to standard fireworks: what makes a great, large-scale outdoor laser show special is the lasting effect!The range of the high power laser pointer depends on the wavelength used, power and ambient lighting conditions. It looks like a cool toy, but the green laser pointer from the DVD drive is pretty much the strongest that the average consumer can get and definitely can't compare to a normal laser pointer.
Light output of 10000mw laser pointer
The last two times I took a light from customs, I was asked if it was a 10000mw laser pointer and I had to turn on the lights to prove they were flashlights. There are plenty of "powerful" laser pointers in the UK. This means at least customs issues can be completely ignored. The photo above shows an eye view of (refracted) light from a green laser pointer. Beneath this, the webcam also shows white dots between green light spots: infrared radiation! During a shopping spree, physicists stumbled across cheap green laser pointers that were advertised as having 10 mW light output and were not allowed to be sold in many countries.
This is where the laser pointer comes into play. This is a mini flashlight that works with a laser beam. Laser technology can create a small spot of light and point it very precisely at various objects. You can't do this with a traditional flashlight. Since such laser pointers are also small - some can fit on a stack of keys - they are also much more convenient than walking sticks. I rarely use a flashlight, so I prefer a laser pointer. Mufflers are also useful. I stumbled across a site that has a laser pointer built into the gun, i.e. where the recoil spring is "overtightened" there is a new piece of metal integrated with the laser pointer.
