Performance Has Reached The International Leading Level Green Laser Pointer
Semiconductor lasers have been developed for more than 60 years. From the perspective of green laser pointer efficiency, cost and output power, it is an excellent laser light source. But there are few that can be used directly. The reason is that it is not easy to use. Zheng Wanhua's research goal for many years is to make semiconductor lasers “easy to use”, which is why she persisted. From investing in the academician Xu Zuyan to working at the Institute of Semiconductors; from her PhD in Hong Kong to MIT in the United States As a senior visiting scholar; from one-person research to the establishment of a research team that can overcome difficulties; Zheng Wanhua has always worked hard to improve the performance of semiconductor lasers. In the end, he has made an independent decision on the performance of semiconductor lasers in microstructure control. The road of development. The key performance of the researched semiconductor laser has reached the international leading level. The laser developed by her has also played an important role in many projects. It has developed a number of green laser pointer applications.

During multiple inspections and green laser pointer project reviews. Experts and leaders have commented on Zheng Wanhua's team research. This is one direction where it is possible to achieve 'overtaking in a curve'. Zheng Wanhua said that to achieve "curve overtaking" in this direction depends on a strong and innovative research team. Most of the team members are trained by themselves. More than 80% of the equipment in their laboratories are domestically produced or developed by themselves. Compared with most semiconductor laser laboratories and the industry, their conditions are not dominant, and some seem to be very Lagging, even at a disadvantage. But we have the possibility to achieve 'change lanes and overtake'. The so-called "change lane overtaking." It means that the team dares to innovate independently in research. It has taken a more distinctive green laser pointer development path.
Let's take a look at the power supply specifications. When we choose the laser pointer, there are instructions in the manual. It can be divided into two parts: wavelength and power. The wavelength unit is NM. The commonly used wavelength is 532nm. There are other different wavelengths, such as 405nm, 650nm. Otherwise, power is the key factor of the laser. The minimum power is about 3MW. The strongest power can reach 1000mw. But he has no right to use it, except for special purposes, which requires permission to use. In the market, a laser pointer less than 300mW can be used. 3. The laser pointer has many colors, such as green, red, blue and purple and blue.
