Chapter 915: Advanced Atomic Clock!

Near the end of July, Yang Jie appeared in Jinshan Atomic Clock Technology Company in Zhangjiang Science and Technology Park, Jinshan City. →+?8→.? Eight** read?? Book, .↓≥

This time, Li Kaiyuan wanted to inspect Jinshan Atomic Bell Technology Company, and Yang Jie also attached great importance to it, and rushed over with Song Manli, Uncle Xiao, Hu Huanzhi and others.

At ten o'clock, Li Kaiyuan drove into the company's gate in a fuel cell version of the minibus produced by Zhongyuan Automobile Company.

Seeing Li Kaiyuan, who was wearing a white shirt, get out of the car, Yang Jie also showed a smile on his face and walked forward quickly.

The TV reporter who followed at this time also filmed this scene.

In the company's product display area, Kingsoft Atomic Clock Technology Co., Ltd. also displayed products such as hydrogen atomic clock and rubidium atomic clock.

These products have been used in many products, and they are the best companies in China in this regard.

After Huaxing Group and Jinshan Astronomical Observatory established this company, the technology has been developing high-precision atomic clocks on the ground and on board according to Yang Jie's intentions, providing atomic clocks for the Starlink network, and also developing chip-level atomic clocks, because this is a powerful tool to open the market.

In recent years, Kingsoft Atomic Clock Technology Co., Ltd. has developed an atomic clock device that is smaller than a matchbox, and the core component of the atomic clock is half the size of a fingernail, which is very precise.

Now this type of atomic clock has formed a series, divided into time synchronization series and frequency series products, these two series of products the company now provides millions of pieces every year, mainly used in communication base stations, servers, satellite terminals, like such an atomic clock is sold at more than 20,000 yuan, bringing more than 20 billion revenue to the company.

It is these two series of products that make the company the largest supplier of chip-level atomic clocks in China, and at the same time, the equipment equipped with these chip atomic clocks of Huaxing Group has obvious advantages in data transmission synchronization accuracy, so that people can not feel the existence of delay.

Huaxing Group is the first company to use chip-level atomic clocks, and the level of synchronization technology is one or two orders of magnitude higher than that of crystal oscillators, so the performance of the new equipment on the market in the past two years is much higher than that of similar equipment.

This forces equipment manufacturers at home and abroad to prepare to use chip-level atomic clocks, but now there are very few companies that can commercially produce chip-level atomic clocks, and there is a company in China that can achieve production.

Now there are several research institutes in China that have developed atomic clocks, which also see this huge market, and they are also following behind in the development of chip-level atomic clocks.

When Kingsoft Atomic Clock Technology Co., Ltd. was first established, there were only a few dozen R&D personnel, and in a few years, the number of personnel in this area has increased to more than 300, and most of the top talents in this field in China have been recruited.

Li Kaiyuan was also quite happy to hear that the revenue of Kingsoft Atomic Clock Technology Company had exceeded 25 billion yuan in less than five years since its establishment, and it was definitely a high-tech company.

The chip atomic clock is mainly used in the field of satellite navigation, compared with the crystal oscillator time scale, the aging speed of the chip atomic clock is slower, which can effectively reduce the code search time, thereby reducing the waiting time of the navigation receiver, and realize the direct capture of the short code, and can also effectively improve the anti-interference ability, reduce the number of satellites required for positioning.

In the operation and management of the communication network system, timing and time unification are indispensable parts.

Compared with traditional methods, the application of chip atomic clocks can provide more rugged and high-bandwidth devices, greatly reducing network latency.

At the same time, the anti-interference ability of the chip atomic clock is very strong, because the traditional electronic warfare equipment increases the frequency of co-location interference between the radio frequency communication system and the satellite navigation system because of the high energy density electromagnetic interference, but the chip atomic clock is installed, and the equipment time is consistent, which will make the use of the system in an orderly manner and can effectively avoid interference.

In addition, the underwater environment makes it impossible for users to rely on satellite navigation systems to obtain accurate time information, and the improvement of the stability of the time-frequency signal of the chip atomic clock, especially the excellent stability performance, will enable underwater users to maintain accurate time autonomously for a long time, and benefit from time consistency maintenance, communication, underwater navigation, waterway repair, etc.

After listening to the introduction of the company's chief scientist in terms of technology, Li Kaiyuan also nodded frequently, and he also encouraged the team of Kingsoft Atomic Clock Technology Company.

Later, in the company's laboratory, the technical team also demonstrated for the first time the prototype of the most advanced atomic clock principle that is being developed.

The new all-optical atomic clock principle that the scientists are working on is that a single cooled liquid mercury ion is connected to a femtosecond laser oscillator equivalent to a pendulum, and the clock is equipped with optical fibers that decompose the optical frequency into microwave frequency pulses that can be recorded by a counter.

To create such an atomic clock, it is necessary to have the technology to capture the corresponding ions and make the captured ions static enough to ensure accurate reading of the data, and to be able to accurately calculate the number of "ticks" at such a high frequency.

The quality of such a clock depends on its stability and accuracy, that is, it provides a constant output frequency and aligns its measurement frequency with the resonant frequency of the atoms.

In order to meet this requirement, femtosecond lasers need to be manufactured, and in order to create short-pulse lasers, it is necessary to have very deep knowledge of the Corer lens mode-locking principle and laser cavity type.

The company has also organized a technical team to specialize in the research and development of femtosecond lasers, which may take more than ten years to make a breakthrough, but Yang Jie is very patient with this.

In fact, some foreign research institutions are also conducting research in this area, and the principle is similar to everyone, but there is a long way to go to make the principle prototype come out of the laboratory and become a product.

After all, the environment in which the product is used is very complex, and the experimental prototype needs to solve countless engineering and technical problems to meet these use environments when it comes out of the laboratory, and it cannot be produced without the help of a large number of experienced engineers and technicians.

The reason why Kingsoft Atomic Clock Technology Co., Ltd. was able to produce chip-level atomic clocks was to do so with the support of Huaxing Group's strong precision machinery manufacturing and microelectromechanical machining technology.

Of course, other research institutes are also working on another advanced atomic clock, which uses 1 million liquid metal cesium atoms to react to microwave radiation to control the movement of the clock hands. The clock hand moves about 10 billion times per second, and the faster the clock hand moves, the more accurately the clock calculates the time. But the high-speed electronics used in cesium atomic clocks can't count more clock hand movements.

In principle, this technical solution of Kingsoft Atomic Clock Technology Company can be 100 to 1000 times more accurate than microwave cesium atomic clock, and it can calculate the shortest time interval in history.

The company's technical team believes that this kind of clock can improve the application level of aviation technology, communication technology, such as mobile phone and fiber optic communication technology, and can be used to adjust the precise orbit of satellites, aviation in outer space and connect spacecraft, etc., and can be used for interstellar voyages in deep space exploration.

Yang Jie has always liked to use these grand ideals to encourage the technical team, because material stimuli are limited, and only ideals can stimulate the strong motivation and creativity of the R&D team. 11
