Here is the design and technology of Laser Pointer

Each of which will respectively control one of the two laser beam lights of Laser Pointer .  
Figure (5-16) shows the curve of their relationships. Be seen by the curve, when the discharge current is small, the output power with discharge current of about a fourth power relationship. With the increase of discharge current, the output power gradually becomes proportional to the square with the discharge current. This is because, as the current density increases, the temperature of the gas increased laser broadening of the spectrum, and thus gain with the current growth rate slows down. The output power curve with the change of discharge current. Dye lasers. 1966, the first giant pulse ruby laser pumped aluminum chloride phthalocyanine Jing (CAP) and cyanine dyes, obtained by stimulated emission of radiation. Since then, the dye laser has been rapid development. Then the customer can know the quality and performance of Laser Pointer better.Resulting increase in electron temperature (average kinetic energy), the excitation rate increases; capillary diameter decreases, the electrons and ions of the compound wall intensified in order to maintain the discharge current is constant, we must increase the electric field, the resulting electronic The temperature will help to stimulate. The other hand, the pd value is too low will reduce leaving the output power of He and Ne atomic number is too small. Optimum discharge conditions, the gain coefficient of the work material and the capillary diameter d is inversely proportional to. By stimulated radiative transition to the Ne atom laser level with the spontaneous radiation transferred to the metastable 1S level, then return to the ground state by way of energy release and wall collision. If the diameter d increases, reduce the chances of the atom and the wall collision. Here is the design and technology of Laser Pointer . 
A software error, can not simply be attributed to an individual's responsibility, some errors may be produced not for technical reasons, may come from chaotic project management. Should analyze the processes of software projects, process improvement to find the cause of the error and improved measures. Misunderstanding number three: software testing do not ask random personal multi-line. Many people think that software testing is to install and run the program, the little mouse, press the keyboard. This is caused by specific techniques and methods do not understand software testing. Along with the improvement of the development of software engineering and software project management experience, software testing has formed an independent technical disciplines, evolving into an industry with huge market demand. The manufacturer should try the best to improve the design and technology of Laser Pointer .
