Details Discussion of green laser pointer
And length of time the laser has become the new standard, any future high-precision watches and meter stick to a specific wavelength can be used to calibrate the laser beam. Laser applications in nuclear energy will play an active role. Optimistic experts estimate that by 2020, a powerful laser will produce safe and economical nuclear fusion, which is similar to the process of nuclear reactions inside stars. If realized, thermonuclear fusion will bring enormous social and economic benefits, the energy crisis will no longer exist. By that time, a bucket of water after hydrogen fusion power generated is sufficient to use a city. The design liaison meeting of green laser pointer will be held again for some reasons.
Laser processing applications in the microelectronics industry. Non-contact laser processing method of processing, high efficiency, no pollution, high-precision heat-affected zone is small, so in the electronics industry, especially in the microelectronics industry has been very widely used. Laser trimming: integrated circuits, the resistance of the sensor is a layer of resistive film, making the error of ± 15-20%, only the correction of high-precision device that can improve the yield. Laser beam can be focused to a small, energy concentration, processing of the adjacent heat affected a very small component, does not produce pollution, but also easy to use computer-controlled, so to meet the fast-trimmed resistor so as to reach an accurate value for the purpose intended. Processing of the laser beam is focused on the resistive film, the material vaporized. When the first fine-tuning resistance measurements, the data transmitted to the computer, computer based methods of pre-designed trimming instructions laser beam positioning allows the path cut by a certain resistance, until the resistance reaches the set value, the error reduced to 0.05%. Some technical parameters details of green laser pointer should be further discussed.
The resistance can also be used sheet of laser correction capacitor capacitance, the principle is the laser beam is focused on the capacitance of the electrode, so that an area of high temperature vaporization decreases, until reduced to a predetermined capacitance value. ESI U.S. is the world's largest manufacturer of laser trimming machine, the major integrated circuit manufacturer has provided thousands of laser trimming machine.
