In recent years, laser power has increased dramatically, and so has its price. Adults can buy green laser pointer to operate them. Many lasers have increased their power by 10 times or more. Laser Pointers and toys, safe use tips. Logo and visual glasses: Green is the brightest human eye, perfect for astronomy, used for night photography... Blue is also very bright sample, red and purple appeal will be more ugly, less boring and perfect for interior use as intro. Experimentation and combustion: Blue lasers are better suited for combustion experiments because they have more energy than their near-ultraviolet wavelengths. Followed by purple and red lasers, which are also highly flammable. The green laser came last, not as powerful as the other one. Some organic dye molecules have achieved tunable laser operation over an almost continuous frequency range. The molecules of these dyes have a large number of spectral lines, and each of them has a larger characteristic frequency propagation than the diffusion of gaseous atomic lines. By covering these lines in the dye, the dye laser can be tuned to produce the laser action used in the laser spectrum.
The widely used dye is Rhodamine 6G, commonly known as Rh6G. It is one of the strongest fluorescent materials known, and early astronauts used it to mark the position of their capsules as they landed in the ocean. The unique properties that make it useful in such exotic applications also make it popular as a laser medium. Another type of dye used for spectroscopy is called a "cyclic dye" and can be tuned essentially continuously. This is similar to the car enthusiast who likes to supercharge the engine or add race-style spoilers and body panels. He is also close with computer hobbyists who overclocked or customised water-cooling systems. None of these hobbies are particularly "beneficial," but they are not harmful hobbies. In addition, some people just like to look at laser beams. The 5 mW beam is very weak. high powered laser enthusiasts often want more visible and powerful beams they can afford. Maybe they like Star Wars or Star Trek, and they like to have their own "lightsaber" or "phase shifter" to work with.
