The certification of green laser pointer is the important check item

In the industrial field, of Nd: YAG crystal to get high power laser output is widely used in materials processing. Lasers for materials processing sales around the world continued to grow, high-power laser sales to remain strong, the main reason is the world's car manufacturers continue to introduce new models, parts and components increased use of laser processing, laser processing of a gradual shift from turned to using C02 laser using Nd: YAG laser. According to Laser Focus World, in 1997 the world for the materials processing of Nd: YAG laser, with sales of $ 117 million in 1998 for materials processing Nd: YAG laser on sales of $ 289 million in 1999, is used to material processing of Nd: YAG laser, with sales expected to grow by 8 percent, reaching $ 312 million.  green laser pointer can add some mysterious atmosphere to the entertainment place.
Medicine and the medical field, has been one of the important applications of the Nd: YAG lasers, Nd: YAG laser medical equipment has been widely used in all laser medical equipment. This is not only because of the repetition rate and high average power. More important is its 1.06μm wavelength can be used quartz fiber light guide, so to be soft transmission power of the transmission line. According to the statistics of LaserFocus World, the world of solid-state lasers in medical applications, in 1997 annual sales of $ 159 million, 1998 sales of $ 270 million in 1999 sales expected to reach $ 310 million. The certification of green laser pointer is the important check item of led flash light .
Rare earth in the pumped laser crystal the eighties semiconductor laser (LD) has made significant progress to become a new type of solid-state laser pump source. The variety of available diode-pumped laser crystal, in addition to the traditional laser matrix of YAG, YLF outside, as well as high-gain YV04, etc., activate the ion in addition to traditional Nd from the outside, as well as of Yb, Ho and Tm and Er ions. Yb: YAG has many features for high-power LD pumped, may develop into a high-power LD-pumped laser material. Of Yb: S-the FAP crystals in the future may be used in laser fusion, laser materials, a cause for concern. Tm: YAG, Ho and Tm: YLF, Ho: YLF laser crystal emission wavelength suitable for application in the military.  green laser pointer is effective in aiding teacher’s teaching.
Prospects for the development of rare earth in the tunable laser crystal. In addition to the above crystal doped tunable laser crystal, as well as of Cr, and Yb, Ho: YSGG laser crystals and other. Of Cr, Yb, Ho: YAGG the wavelength of the laser crystal in between 2.84-3.05μm continuously adjustable. Missile infrared homing warhead used on the statistical world is the 3-5μm MWIR detector, so the development of Cr, Yb, Ho: YSGG laser crystals, can provide effective mid-infrared-guided weapons against sources of interference, with far-reaching military significance. In addition, 3-5μm infrared light can be used to remote detection of chemical substances, and therefore can be used for anti-chemical warfare and environmental protection. The limitation of owning green laser pointer is included in the guide book.
Rare earth in the new wavelength laser crystal. Consolidate the development of existing products, of Ho: Cr: Tm: YAG, Ho: Er: Tm: YLF and Er: YAG, etc., to further improve the crystal quality, high-volume production. Should continue to strengthen the new band to explore the value of the laser. Experience and advice. China earlier carried out the research and production of laser crystals, including the North China Institute of Optoelectronic Technology, is the main unit. North China Institute of Optoelectronic Technology, long-term commitment to military tasks, with a strong research capacity, has a strong product development capability, not only made many achievements in scientific research, and made great achievements in the transformation of scientific research. Some other green laser pointer products will create the laser radiation.
