Green laser pointer is in the pen shape

Can be applied to Blu-ray Disc HD-DVD next generation optical disc 2 layers of 12-speed or four layers of six-speed, high-speed read and write. The current circulation of products on the market, the output power, however 200mW, 420mW of output power close to 2 times. The output power of 1W blue laser projector for the use of laser light output power increased to 2 times. Nichia Chemical Industry published the background and the use of these high-power laser technology. 420mW of output power product production in 2009. On the output power of 420mW blue semiconductor lasers products. Nichia Chemical Industries, said the technology development has been completed. The body color of green laser pointer  is black.
Life to ensure that more than 5000 hours, the electrical characteristics such as product performance has reached the practical level. The company plans to mass production in January 2008 250mW products supplier, one year after production quantities 320mW products, the 420mW Products of the 2009 mass production of this release. According to Nichia Chemical Industry, before the appearance of the output power of 250mW products, the development of next generation optical disc device has been affected by the blue-violet laser power limit, although the manufacturers want to improve reading and writing speed, but because of the constraints of the semiconductor laser output power, You can not speed up the development of high-speed read and write device speed. By a substantial increase in the blue-violet semiconductor laser output power to 420mW. This kind of green laser pointer  has the rubber finish on the top of the body appearance.
Will not produce the power limit in the future, although the 12-speed Layer 2 or Layer 4 six-speed high-speed read and write standard has not been specific decisions. But the company stressed that as long as the output power of 420mW blue-violet semiconductor laser can be fully supports high-speed. The output power of 1W of products from the September 2008 mass production. Display-oriented use of the output power is 1W blue semiconductor laser, sample delivery time in March 2008 and mass production is scheduled in September. Mainly for the use of red, blue and green laser to improve the color reproduction of the projector light. Infrared semiconductor laser CTP platesetters and the contrast of the blue-violet semiconductor laser.  green laser pointer  has the mid open design.
Thermal CTP using the infrared semiconductor lasers. 830nm infrared diode laser used in thermal CTP development from the early power of 1W to 40W solid-state lasers, semiconductor lasers 1W (2W) are now back, this is because life is too short for the 40W solid-state lasers, can not guarantee production . In order to meet the requirements of the plate velocity is generally 20-30 only laser to form a laser bar, light valve technology for sub-beam River imaging exposure control. Because exposure is the use of light valve to control each laser alone can not switch, the infrared laser power is turned on, needs to warm up to enter the work state, so long as the production status must be turned on. The customer can replace the batteries from the middle part of   laser pointer .
