Laser Pointer Metal

The working of the high power green laser pointer

The infrared laser output in the case of a kaleidoscopic green laser pointer gets focused into a small crystal of Neodymium doped Yttrium ortho Vanadate. This then turns into a longer wavelength of 1064nm. This 1064nm output beam gets absorbed in an adjacent crystal of Potassium Titanyl Phosphate that resonates at twice the pump light frequency in order to produce an output of 532nm green laser light. A multilayer interference filter in the 100mw green laser pointer pen removes residual infra-red light. The output is focused and collimated into a thin parallel beam. Both these crystals are artificially grown, and must be cut, polished, and multi-coated to very small tolerances.

The kaleidoscopic green laser pointer can be custom produced to your specifications. They are the highest quality green pointers on the market. The high power green laser pointer is constructed of strong metal tubing with a pocket clip. The laser power output is guaranteed to be between 3 and 5 mill watts, that is typically very close to 5mw. The kaleidoscopic green laser pointer is powered by two AAA alkaline cells. They work very hard when the pointer is on, as they supply about 280 milliamps.

The 100mw green laser pointer pen come with one set of batteries in a hinged black metal presentation case. This should be treated carefully and not dropped or even banged around. The kaleidoscopic green laser pointer is warranted against defects for six month. All the green class IIIa pointers that are sold are designed for momentary use in pointer service. This means that they are not to be kept on continuously. About one minute should be the maximum. After being kept on for this long, the high power green laser pointer should be allowed to rest for a similar period. In case the pointer is kept on longer or continuously it can even dim out. However, the kaleidoscopic green laser pointer will not be damaged as the control circuit will prevent current from rising to a harmful level.

Safety precautions must always be followed while using the high power green laser pointer. The beam of the kaleidoscopic green laser pointer should never be allowed to enter the eye. Even though instant permanent blindness will not occur with a momentary, glancing exposure, but visual damage can occur if the beam is allowed to enter the eye and it falls upon the same area of the retina for more than 1/4 second. This is an unlikely occurrence, due to the aversion and blink reflex.
