The weak and narrow absorption characteristics around 880nm have become research hotspots for high-brightness pump diodes, which can achieve spectral stability. These higher-performance green laser pointer can directly excite the upper laser level 4F3 / 2 in neodymium, reduce quantum defects, and improve the extraction of fundamental modes with higher average power, otherwise they will be limited…

However, these green laser pointer are far from practical devices. In order to promote the birth of high-power semiconductor lasers, the integration of different technologies must be achieved. Key technological innovations began with an understanding of direct bandgap semiconductor materials and crystal growth technologies. Subsequent developments include the invention of dual heterojunction lasers and subsequent developments of…

A company spokesperson said that the ATHENA laser weapon system is likely to be used by the military because it can disrupt its operations before hostile ground forces approach. According to a company spokesman, the latest test is the first field test of the green laser pointer weapon. The development of this laser weapon relies on a…

The laser gyro is a combination of many high-precision tip technologies. Mass production is to “solidify” these high-precision extreme technologies. Along the way, they finally saw the dawn of success-the first laser gyro production line was built in their hands, and the accuracy and reliability of the product reached the world advanced level. In order…

Whenever you experience hardships, surprises are always unexpected. In 1978, Gao Bolong led the research group to make unremitting efforts and finally successfully developed the first prototype of the laser gyro laboratory principle. This achievement solved a lot of theoretical and technical problems, and laid the foundation for the further development and production of laser…

The development of laser gyro is not only a new green laser pointer field, but also a worldwide problem. With the scientific research conditions and technological level at that time, it is even more difficult to succeed in development. For the difficulty of developing a laser gyroscope, Gaboron is clear. The talented student who graduated from Tsinghua…

After being safely amplified to a higher energy level, the light can be compressed again by another grating. The end result: more powerful pulses and lossless amplifiers. This “chirped pulse amplification” has become a basic feature of high-power laser pointer. In 1996, it enabled researchers to use lasers to generate the world’s first PW-level pulses. Since…

Higher repetition rates are also critical for driving particle beams with high-power laser pointer. In one approach, a strong laser beam can convert a metal target into a plasma. The electrons released by this process in turn eject the protons from the nucleus on the metal surface. Doctors can use these proton pulses to destroy cancer,…

At present, electronic countermeasures have evolved from auxiliary support operations at the beginning to indispensable main battle support operations, and the status of “leadership and execution” has gained popular support. Offensive and defensive capabilities in the electromagnetic field, such as regional interruption, electronic destruction, and incidental disturbance, have become a standard measure or even a…

Not only has it played a huge role in the fields of communication, navigation, detection, etc., but it has also become more and more obvious against “genes” and has become a new “burst point” for signal reconnaissance and electronic attacks. In recent years, advanced technological projects such as cognitive electronic warfare, distributed interference, battlefield wireless…
