Changchun optoelectronic national industrial base has a certain industrial base. The end of 2002, the city Optoelectronic information enterprises reached 280, the total assets of 9.9 billion yuan. Optoelectronic industry base construction in Changchun City, the main objectives are: to the information display device and its upstream and downstream products as the core to form the largest information industry base. Expansion of optoelectronic devices and materials, optical instrumentation, defense Optoelectronics three key areas to form a rational structure of the Changchun optoelectronic industry base; covers an area of 50 square kilometers south of Metro construction in Changchun Optoelectronic Information Industry Base core area, while planning the 50 square km extension area. Material of  laser pointer is the hard aluminum.As of September 2002, Guangzhou enterprise engaged in the photovoltaic industry a total of 325 of them engaged in the production of optoelectronic technology, research and development enterprise 158, another 167 enterprises engaged in optoelectronic products sales and service. Guangzhou has formed the optical display, optical storage as the core of the photonics industry group. Photoelectron output in the first half of 2003, the Guangzhou Science City, about 70 billion yuan, is expected this year will grow by about 50%. Guangzhou City is planning the construction of optoelectronic industry base in Nansha Development Zone, in accordance with the "development started in 2001 livelihood nano-engineering, the establishment of the Southern Center for Nanoscience and development strategy, is through the implementation of the" 4412 Project "(the development of nanophotonic materials and devices industry four areas of focus. The original purpose of using multimedia facilities including  laser pointer is making teaching more convenient.All these parts and components of laser pointer should be strictly inspected
Establish a the nanophotonic base 4 R & D base, build a Guangzhou nanotechnology information network consisting of nano-technology support service system), to promote the development of nanotechnology and industry. To 2003 in the organization and implementation of the Nano 30 projects, estimated 2 to 3 years is expected to have a number of projects in industrial production, output will reach 2.5 billion yuan in five years. Plans to 2007, fighting for the formation of 3 over 10 billion yuan, 10 over 50 billion yuan output value of the scale of optoelectronic enterprise "aircraft carrier", the city's optoelectronics industry output will reach 550 ~ 650 billion, an annual growth rate 28% ~ 35%, 11 to 130 000 job creation. It block the progress of the traditional classroom education if not utilizing  laser pointer .
