The quality group of laser pointer will host the quality

The quality group of laser pointer will host the quality analysis meeting of laser pointer .
Hollow fiber with air (or gas) as the core of the thin tubular fibers, laser reflection in the upper side of the tube wall spread. This hollow fiber is not in addition to fiber end reflection losses, which can be very high transmission efficiency. The typical structure of the hollow fiber as shown in Figure 21 indicates. Figure 21 (a) rectangular hollow metal waveguide, it is the longest study of history. Present as a high-power laser optical transmission, is expected to figure 21 (b) and Figure 21 (c) shape. Figure 21 (b) for the single crystal Al2O3 hollow waveguide. Figure 21 (c) transparent metal coating on the inner wall of the hollow dielectric fiber, the fiber support tube can be metal or glass. The quality group of laser pointer is composed of 10 employees.
Blue-green laser communication with the deeper penetration of sea water, high transfer rate, information capacity, good for hiding, does not affect the submarine's mobility and real time characteristics, is the future direction of development of potential communication. The use of blue-green laser submarine communication has far superior than the traditional means of communication of the potential features. Laser vector potential can be divided into communication by satellite laser communications systems and airborne laser communication systems. Onboard system can cover a global scale, more suitable for the communication of strategic missile submarines, airborne system is more effective for tactical submarines. The innovative concept of laser pointer is very advanced.
To detect and accurately identify underwater threats must be equipped with advanced target sensing device. Blue-green laser using underwater sensing devices, underwater sensors available than other higher recognition accuracy and positioning capabilities, some have conceived, if blue-green laser equipment on the submarine underwater sensing device makes use of submarines as radar as the use of high-energy blue-green laser penetrates deep dark water, seek and find the target, the target can be tracked and guided torpedo attack. Of course, to achieve this vision, there are still many technical problems.
