How powerful is the most powerful laser in the world? As far as I know, the most powerful green laser pointer, the ruby laser, is used by the US Navy. With a power of a few megajoules. They are designed to shoot down all types of incoming missiles. This is derived from memory, and they may have been surpassed since then.
Since reflection and absorption are interactions with matter, they are affected by the fluctuating characteristics of matter. Therefore, single frequency (monochromatic) waves are better handled, and the issue with intensity is the reason why only lasers and ultrasound are used for narrow beam applications. Using the same argument, we should be able to explain why all gamma rays are just narrow beams or self-focusing. This is something worth studying. If anyone knows.
My dog eats only when I play with the laser pointer, because she likes to be entertained while eating, and I just discovered that they are bad for the dog. What substitute can I use to help her eat? Your dog will eat when he is hungry. Make sure to provide food twice a day for 10 minutes each. Then pick up the food. Remember, dogs are metabolically close to wolves, and wolves are the eater of feasts and famines. They might kill the gorge and eat no food for several weeks. So be patient and change the rules of the game that your dog has started.
I have a 5000MW green laser pointer, but it does not burn. Will the magnifying glass help my laser pointer burn black things? The green laser emitting 5W power will be very bright. You can aim the beam at a piece of metal or a brick, it will be very bright, you can’t see it. The lens really helps the way it helps when focusing the sun. But I guess your laser will not produce 5W of power. If so, you can burn things like paper or wood effortlessly.
Among related issues, one can mention beam steering technology used as a hybrid source. In this case, many point sources have been adjusted in phase and amplitude so that the front of the beam has certain characteristics or variable positions. This can be used to increase the intensity and decrease the intensity, for example in a cancer killing beam. Or it can change the position of the beam spot to scan an area or a volume. This principle can also be used in receivers and radar or pattern recognition and replication applications.
