The features of a green beam laser pointer
The dot of a 50mw green laser can be seen at much greater distances than that of a red laser pointer. The green star laser pointer has a very bright green laser at 532 nm wavelength. It has an output power that is less than 5mw. This means that it is a class III a laser product. The range of 50mw green laser is approximately 9,000 ft in darkness. The laser has 1.1 mm beam diameter at source. It has a push button switch.
The green star laser pointer has a solid, Heavy Duty construction. It has a constant wave output and not a pulse output. The 50mw green laser requires 2 "AAA" batteries in order to operate.
The green beam laser pointer can be used for pointing at the sky, projection on low clouds, as well as signaling, and highlighting potential explosives. It is 5.6" x .5" in diameter.
It should be remembered that green lasers are very powerful. Pointing them at aircrafts may even land you in jail. So they should be used wisely
Green star laser pointer is significantly brighter than a red laser pointer because of its unusual color.
After a telescope, this can be considered as the best astronomy educational tool. At night this AAA battery powered 50mw green laser pointer can appear to touch the stars millions of miles away. As compared to a red laser pointer, the green beam laser pointer remains visible and is able to penetrate the air much farther. Because of its particular spectrum you will be able to see the beam and not only the end dot. On a clear night it can easily shine a dot that can be nearly a mile away. With its sharp laser beam you will be able to pinpoint the exact star that you want. This greatly accelerates mapping as well as learning the constellations.
The problem with green beam laser pointer has been their stiff price. Only recently have they dropped their price. Manufacturing green beam laser pointer is more of an art than science. This means that their actual power output tends to vary by final pointer.
The green star laser pointer is a very powerful laser pointer with star caps. The cap creates a variety of patterns when you are turning it around. And once you screw off the cap, it becomes a pure laser pointer. This is a cool environment creator for parties and discos.

using a laser beam in physics how do I calculate?
Using a laser beam, I melt 1 gram of ice. The frequency of the laser light is 5.1 x 1014 Hz. How many photons does my laser emit, assuming they are all absorbed by the ice?
2.5 x 1019 photons.
8.6 x 1019 photons.
1.0 x 1021 photons.
4.5 x 1021 photons.
The energy of 1 photon, E=hf, is
5.1 x 10^14 X 6.6 x 10^-34 = 3.4 x 10^-19 J
The latent heat of fusion of water is 334J/g, so you need 334J to melt the ice cube.
To provide 334J, you need 334/(3.4 x 10^-19) = 1.0 x 10^21.

Beam: The Race to Make the Laser $53.68 In 1954, Charles Townes invented the laser's microwave cousin, the maser. The next logical step was to extend the same physical principles to the shorter wavelengths of light, but the idea did not catch fire until October 1957, when Townes asked Gordon Gould about Gould's research on using light to excite thallium atoms. Each took the idea and ran with it. The independent-minded Gould sought the fortune of an independent inventor; the professorial Townes sought the fame of scientific recognition. Townes enlisted the help of his brother-in-law, Arthur Schawlow, and got Bell Labs into the race. Gould turned his ideas into a patent application and a million-dollar defense contract. They soon had company. Ali Javan, one of Townes's former students, began pulling 90-hour weeks at Bell Labs with colleague Bill Bennett. And far away in California a bright young physicist named Ted Maiman became a very dark horse in the race. While Schawlow proclaimed that ruby could never make a laser, Maiman slowly convinced himself it would. As others struggled with recalcitrant equipment and military secrecy, Maiman built a tiny and elegant device that fit in the palm of his hand. His ruby laser worked the first time he tried it, on May 16, 1960, but afterwards he had to battle for acceptance as the man who made the first laser. Beam is a fascinating tale of a remarkable and powerful invention that has become a symbol of modern technology. |
