The use of femtosecond lasers for ultra-fine processing is another important application research field of femtosecond laser pointer technology besides the use of femtosecond lasers for ultrafast phenomenon research and super-strong phenomenon research. This application has only been developed in recent years, and there have been many important developments.
Different from femtosecond superfast and femtosecond super research, femtosecond laser ultrafine processing is closely related to advanced manufacturing technology, which can play a more direct role in promoting the development of certain key industrial production technologies. Femtosecond laser ultra-fine processing is an extremely eye-catching frontier research direction in the laser and optoelectronic industries in the world today.
Research on new lasers: Laser rangefinders are the starting point for laser applications in the military, and their application to artillery systems greatly improves the accuracy of artillery shooting. Compared with radio radar, lidar has a small divergence angle and good directivity, so its measurement accuracy is greatly improved.
For the same reason, there is no “blind zone” in lidar, so it is especially suitable for tracking and measuring the initial stage of missiles. However, due to the influence of the atmosphere, lidar is not suitable for searching in a large area, and can only be used as a powerful complement to radio radar. There are also precise green laser pointer-guided missiles, as well as the use of laser weapon technology used on the simulated battlefield. On the battlefield of the actual laser combat exercise, it resembled the actual war scene.
The advantages of laser weapons; no need to perform ballistic calculations; no recoil; simple operation, flexible maneuverability, wide range of use; no radioactive pollution, high efficiency and cost.
Classification of laser weapons: lasers with different power densities, different output waveforms, and different wavelengths will produce different killing and destructive effects when interacting with different target materials. There are many types of lasers with different names. According to the working medium, there are solid lasers, liquid lasers, and molecular, ion, and excimer gas lasers.
