Our green laser pointer is fully legal for laser pointer use in most countries and at just below the maximum allowable legal power limit of 5mW for a pointer in most countries, including USA. We ensure that every high power green laser pointer is hand calibrated and tested to output at least 4.99mw and thus offers the expected stunning power ...

A green laser pointer is a frequency doubled Nd:YVO 4 diode-pumped solid state laser . Nd:YAG can be also made to lase at its non-principal wavelength. The line at 946 nm is typically employed in "blue laser pointer" DPSS lasers, where it is doubled to 473 nm. Physical and chemical properties of Nd:YAG
The green laser pointer beam is generated using an indirect process that begins with a high-power infrared AlGaAs laser diode operating at 808 nm. The 808 nm light energizes a crystal with neodymium-doped yttrium aluminum vanadate (Nd:YVO4). The Vanadate crystal is coated with a dielectric mirror on the diode side, that reflects at 808 nm and ...

Red (660 & 635 nm), green (532 & 520 nm) and blue-violet (445 & 405 nm) lasers. A laser beam used for welding. A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word "laser" is an acronym [1] [2] for " light amplification by stimulated emission of ...
Diffuse radiation (i.e., that which is scattered from a diffusing surface) should not be hazardous. CW emission from such lasers at wavelengths above 315nm must not exceed 0.5 watts. For pulse laser system to be Class 3B their output cannot exceed 125 mJ in less than 0.25 seconds. Class 4. This is the highest class of laser radiation.
On the lower end, you will find red/ orange lasers within the 630 to 680 nm wavelength that have rather short-range and low power output (less than 5 mW). However, there are also red/ orange pointers that boast a range of up to a few miles and power output of up to 200 mW. Green. A lot of laser tools or pointers are of the green spectrum today ...
Electromagnetic frequency, f, is equal to the speed of light, c, divided by wavelength, l, or f = c / l. In this case, f = (299,792,458 m/s)/ (532 nm) = 564 THz, or 564 X 1012 Hz, or 564 X 1012 s ...

Furthermore, some lasers emit more than one wavelength of light, and this may be a particular problem with some less expensive frequency-doubled lasers, such as 532 nm "green laser pointers" which are commonly pumped by 808 nm infrared laser diodes, and also generate the fundamental 1064 nm laser beam which is used to produce the final 532 nm ...
Question 1 1 pts Green laser pointers emit radiation at 532 nm. What is the frequency of this radiation in Hz? 8.12 x 1013 5.64 x 1014 1.60 x 1015 9.10 x 1015 1.60 x 1016 Question 2 1 pts Which of the following electronic transitions would emit light energy?
UV light CAN cause problems: cancerous mutations and the like. Visible radiation, like a green laser, is a different story though. Green/visible light lasers ARE dangerous because they pack a lot of energy - burning power - into a small area. That can burn your eyes, or even skin with enough power. Same with any other intense light though.
