Weaknesses (1) R & D dispersion, the uneven level of low-level redundant construction serious. Is an international leader in the research, scientific research units in many areas of the laser crystal materials and devices, but due to lack of materials, devices, laboratory research to application development and industrialization of the complete R & D industrial chain, making China The overall level there is a big gap with international counterparts. Can not efficiently academic advantage through engineering research and development to achieve industrialization, and thus become a regional and industry economic advantages; in the industry, in recent years, China has also emerged on a one hundred laser crystal materials and The device's high-tech enterprises, but the scale is not large, but most businesses similar products in the international competitiveness of enterprises of the few. For this mini size  green laser pointer , the total output power cannot be customized to a very high value.
The critical crystal materials and components performance should be improved, material preparation, processing, testing techniques behind the world advanced level. For the gap between the key indicators of high-power laser crystal with advanced foreign companies in China is not small, high-performance devices such as electro-optical switch crystals, sound and light switch because of the quality, performance and other reasons, the basic dependence on imports. In the field of crystal device fabrication, China is the world's major countries of the crystal processing, higher technical level, but requires sophisticated equipment and highly automated coating field, behind the world advanced level. The United States, Japan is the largest optoelectronic devices manufacturing, with the international market competition and the transfer of world manufacturing center to the Chinese mainland, the United States, Japan, Germany and other optoelectronic giant will wait for an opportunity to crystalline material for optoelectronic devices upstream investments control of resources. The customer can select green laser pointer  according to the power.
Appreciation of the renminbi. So far, the RMB appreciation of 25% from the 2002 exchange rate reform start. From early 2002 to 8.2 yuan / dollar since the 6.65 yuan / dollar. This is the industry market, export-oriented enterprises are a lot of pressure. (4) the rising cost of raw materials. Financial crisis, the demand has not been effective recovery in the easing of monetary policy to stimulate a variety of raw materials prices, as the raw material of the laser crystal materials also inevitable. As follows: Figure 6: schematic diagram of raw materials prices of raw material prices rose by 2003 to less than 17,000 yuan / ton to 33,000 yuan / ton in 2009, nearly doubled up. This will be business to produce a great disadvantage.
