Currently, the anti-strategic missile research and development of laser weapons, or chemical lasers, excimer lasers, free electron lasers and laser radiation transfer. For example: free-electron laser with output power, beam quality, high efficiency, tunable range and so on.Because of its very realistic simulated battlefield environment, MILES system has been proven in combat training has a strong advantage. Therefore, the view of its prospects, the development of laser shooting training device has a very real sense and broad market forces. Negative feedback is a real-time laser power pulse to detect the laser power and laser power required to compare, then control the pumping current size of the xenon lamp as a control. Non-real-time before the negative feedback is a pulse waveform detected by the laser power waveform compared with the set, and then determine the next pulse laser-pumped xenon lamp current size of the control. Power of negative feedback laser welding machine block diagram shown in Figure 2. Compared with the current negative feedback control, the use of laser power of negative feedback, the output laser energy can greatly improve the control accuracy, especially for mass production of them. When inspecting the buildings under construction, laser pointer will be the best choices of the inspectors.
Figure 3 is a joint win 15W laser laser welding machine at the current negative feedback and negative feedback control of laser power state of the laser output energy fluctuations. It can be seen from Figure 3, at approximately the same output power conditions, the current negative feedback instability under the energy greater than 8%, while the laser power output under the negative feedback energy instability less than 3%. Moreover, with the xenon lamp-pumped laser welding machine use time, xenon lamp-pumped electro-optical conversion efficiency will be further reduced, the current state of the output energy of negative feedback will be gradually reduced, the quality control staff often need to detect the output laser energy, thus increasing the cost of production . With the help of laser beam of laser pointer , normal people can also observe the stars at night at will.
The use of laser power of negative feedback, the system automatically compare the size of the output laser energy and real-time compensation pumped xenon lamp current regulation size, so you can ensure that the output laser energy is always in a relatively stable range. In addition, the use of laser power of negative feedback control of laser welding machine is easy to achieve control of laser power waveform, in fact, for different materials, using different laser power waveform, you can make the welding was more beautiful, and sometimes not even using the traditional way of welding The materials can also change the laser power waveform and get better welding effect.
