Chapter 700 Photonic Crystal! Light Manager!
Compared with the disturbances in the outside world, Li Yang turned a deaf ear to the outside world and immersed himself in the research and development of individual laser anti-aircraft guns.
The last test of "Rain of Pear Blossom Needles Quantum Phase Change Shotgun" had good results, and also stimulated his enthusiasm for scientific research.
after all.
Overall.
Ninety percent of the work on the quantum phase change shotgun was done by him independently.
Only some simulation tests utilize the system's capabilities.
The sense of accomplishment has increased a lot compared to before when I relied entirely on the system to complete it.
"Since I can rely on my own strength to independently complete the Torrential Pear Blossom Needle Quantum Phase Change Shotgun, I am also confident that I can develop a single-soldier laser anti-aircraft gun!"
He took a deep breath, cleared his mind of all distracting thoughts, and began to study the individual laser anti-aircraft gun.
"The individual laser anti-aircraft gun is positioned as a single-soldier portable directed energy weapon, mainly targeting low-altitude ultra-small targets."
Li Yang retrieved the inspirations he had collected earlier and some design plans he had made in advance.
"The core technologies and modules of the individual laser anti-aircraft gun are mainly divided into hybrid phase laser emitter, quantized energy core, intelligent thermal management and optical compensation, and neural synchronization fire control system."
After the basic design plan and ideas were determined, he began to optimize each module.
"Since it is a portable weapon for individual soldiers, it must not be too bulky."
"Moreover, laser anti-aircraft guns are different from ordinary rifles. The bullets fired by ordinary rifles are substantial objects. As long as they are within the range, they can be fired at different distances."
"But the laser anti-aircraft gun is different. The laser beam it emits attacks the target in a way similar to burning. Therefore, the wavelength of the laser cannot be fixed, but must be flexible and changeable. It can be flexibly converted into beams of different wavelengths for different distances and different targets."
Li Yang frowned and paused his hand movements slightly.
This problem seems simple, but it is quite difficult to implement.
If it wasn't a single-soldier combat weapon, he could have done it easily in thousands of ways.
only……
Today it is just a handgun that can be carried around, and the weight is strictly limited.
The difficulty of achieving the expected results suddenly increases a lot.
"Install a laser wavelength adjuster to manually adjust the wavelength?"
Li Yang shook his head.
It is feasible in principle, but with the regulator installed, the weight of the laser anti-aircraft gun will be much higher.
Moreover, manual adjustment is inconvenient.
Especially during combat, the battlefield can change dramatically in a matter of seconds.
I am afraid that by the time I adjust the laser wavelength, my teammates will have fallen to the ground and died.
This is completely contrary to the role of an individual laser anti-aircraft gun.
"Light travels in a straight line. If we install several mirrors when it is emitted, so that it can be refracted in different mirror surfaces and then shoot outward, wouldn't this achieve the effect of wavelength adjustment to a certain extent?"
but.
These "mirrors" cannot be static and must be able to withstand the "burning" of the laser.
It needs to be light enough and smart enough so that users don’t need to operate it manually.
Li Yang's brows gradually relaxed, and he suddenly had some direction.
He kept trying various solutions and then continued to test them on the simulation screen on the laboratory table.
Time passes quietly during research and development, and before you know it, a day has passed.
"Although we didn't achieve any gratifying results today, at least we have a clear direction."
He stretched and walked out of the laboratory.
After returning to his own cabin and enjoying the dinner carefully prepared by He Yun, he spent a wonderful night.
The next day.
He regrouped and devoted himself to research and development again.
"Mirror……"
Li Yang tapped the table with his fingers, constantly thinking about what material would be suitable as a 'mirror' for adjusting the laser wavelength.
The 'mirror' cannot be too heavy or too large, and needs to have good laser wavelength regulation.
Its function is to perform "traffic control" on light, regulate the efficiency of light propagation, and at the same time, at the intersection of light transmission, modulate the passage of different light according to the different spectra of light.
The only material that can produce such an effect is...
"Photonic crystal?"
Li Yang's eyes lit up.
Photonic crystal is an artificial material with a periodic dielectric structure. Due to its unique physical structure, it can efficiently regulate the propagation of light.
To put it in an analogy, it's like a semiconductor that can effectively control electrons.
The existence of photonic crystals can make light "obedient" and propagate along the set route.
"If you build a freely variable photonic crystal into the barrel of a gun, you can adjust the crystal structure through electromagnetic fields."
"In this way, wouldn't it be easy to dynamically switch the laser wavelength between the visible light and near-infrared bands?"
Photonic crystals have the ability to regulate light.
It is entirely possible to precisely control the propagation path, localized state, spontaneous radiation, etc. of light by independently designing structural parameters, such as lattice constants and material refractive index.
and.
Since photonic crystals also have adjustable band gaps, the band gap position and width can be flexibly adjusted by changing structural parameters to adapt to different application requirements.
"This material is tailor-made for individual laser anti-aircraft guns!"
Li Yang's hands kept moving, designing the structure of the built-in photonic crystal based on the characteristics of the photonic crystal.
Once the key materials are found, many problems can be solved.
The subsequent research went much more smoothly.
Many of the previous difficulties have been solved.
"Too few low-power laser beams? No problem!"
"It can be solved by using multi-pulse superposition technology!"
Multiple low-power laser beams are emitted with time intervals in the order of picoseconds.
Then it passes through the air ionization channel and is directed to the same focus.
With the help of multi-pulse superposition technology, the power can reach a peak power of megawatts in an instant.
With inspiration and ideas, Li Yang couldn't stop.
Even started to innovate on the original design plan.
"Since they are all new firearms, they can't just be the same as ordinary rifles. They have to be a little bit innovative!"
“For example, the user can quickly lock onto a high-speed moving target without having to physically rotate the gun.”
Li Yang raised his eyebrows and thought it was feasible.
"If you want to do this, you need to add a phased array deflection module to surround the micro phased array launch unit on the muzzle."
"The effect is achieved by controlling the deflection angle of the laser beam through phase difference."
"feasible!"
Li Yang immediately started to operate.
It took Li Yang a week to complete this module.
Then we started to tackle the core part of quantum energy.
"I'm afraid conventional batteries can't support the long-term operation of a single-soldier laser anti-aircraft gun."
"So, micro batteries also need to be optimized..."
