For radio frequency wireless presenter green laser pointer is moreconvenient application and operation

Ring laser shown in Figure 5.7, set the counterclockwise-moving mode of the resonator frequency are output light intensity, respectively, and. The laser tube filling gas to a single neon isotope, and try to draw timely gain curves and populations of the number density inversion of the axial velocity profile; At that time, the laser output beam stability of light, at a time when there will be a beam of light change, the phenomenon of a beam of light goes out, try to explain why; laser tube filled with an appropriate proportion of the gas mixture, to eliminate the above-mentioned beam of light to strong; weaker beam of light phenomena. test to the case as an example to explain why; to make the basic symmetry of the gain curve of the mixed gas, in charge of the gas mixture, Which isotope should be more. The laser function of  green laser pointer can be used to point at the star the stargazer wants to observe or show, highlight the content the customer needs to demonstrate and so on.
Beat frequency between the calculated frequency pulling caused by the two adjacent longitudinal mode with the passive cavity frequency difference between the poor. Gas laser Doppler widening; homogeneously broadened laser. With the rapid development of mechanical, electronic, optical industry, laser measurement system [1] to help solve the problem of diversity and the increasing complexity of the new laser system developed, their cost and development time have continued to increase . At the same time, the increasingly high requirements on the accuracy of the workpiece parameters, the traditional measurement method has been able to achieve the various needs. Some developed countries in the international laser technology [2] The early start and rapid development, which involves all aspects of modern technology, which includes laser diameter measurement.  green laser pointer  is to meet different requirements of the customer in different locations for different purposes.
Traditional static contact measurement can not meet the measurement of the analyte in China from the late eighties and early nineties began to study laser measurement technology, although a late start, but has developed rapidly. The laser detection technology [3], a new research direction in recent years, measurement and control field is a non-contact measurement of high-tech. But the current high-tech industries gradually to a technology-intensive transition, due to the emergence of computer technology, especially the proliferation of computers, the computer technology, network communications technology to large-scale application. More and more factories in the manufacturing process to computer technology. For example,  green laser pointer  can be used to create some very special laser effect.
Communication network technology and automation technology, represented by high-tech, quick access, and play an increasingly larger role, this role has been more than the traditional technology and industry. Laser measuring diameter of facing more and more complex problems, not only have a high measurement speed and reliability, but also to the development of automated, digital, intelligent direction. This is bound to the original static-contact measurements turned to the dynamic, non-contact measurement. Laser measurement applications fall into two categories, required by a class of high-speed movement of the measured object, can not be measured object-contact measurement, such as Fibre La Sita being drawn fiber, the motion is fast. The customer can especially use   green laser pointer    to indicate the direction.
