Femtoseconds can also be called femtoseconds, which is a unit of measurement for marking the length of time. Taking 1 second as a reference, 1 femtosecond is only one trillionth of a second. It can be seen that femtoseconds represent a very short time. Even if light can fly 300,000 kilometers per second in a…

Femtosecond technology innovation in technology and laser pointer application
The accuracy of surgery has been greatly improved. In addition, the effect of femtosecond green laser pointer LASIK myopia surgery is far better than ordinary LASIK myopia surgery, and the postoperative recovery period is greatly reduced. Half-femtosecond laser correction surgery has been verified by accumulated cases in the past ten years and is already a relatively stable…
Internal laser pointer weapon system
There are decades of research behind the energy guiding weapon system. Lockheed Martin has spent 40 years designing and developing electromagnetic energy systems, and by enhancing the energy of the system to create a directed energy defense system. This technology is powered by batteries, generators or existing power sources, and is a kind of spectral…
Israeli fiber laser pointer weapon technology attracts attention
The US “National Interest” website recently published an article entitled “The “Iron Beam” System: How Israel Use green laser pointer to Destroy Enemy Missiles in War.” The article pointed out that the “4-layer missile shield” currently in service with missiles and anti-missiles of the Israel Defense Forces, although advanced in technology, is expensive and difficult to operate,…
US Air Force Research Laboratory develops chip-level phased array laser pointer radar technology
On March 4, the U.S. Air Force Research Laboratory at Wright-Patterson Air Force Base in Ohio awarded a fixed-price R&D contract with a total value of $8.107308 million in La Jolla, California, to develop a chip-size “optical phase”. Array and Lidar” system. It is understood that the system utilizes the results of the first phase…
The interaction of water and light emits laser pointer for the first time
The Technion-Israel Institute of Technology issued an announcement on the 29th, stating that for the first time, researchers at the university have proved through experiments that the interaction of water and light can also emit laser light, building a “bridge” between two research fields that were previously considered unrelated. The new “water-wave laser” can be…
The future development of ultra-fast laser pointer technology
With the rapid development of laser technology, ultra-fast lasers have appeared in people’s sight. It has unique ultra-short pulse and ultra-strong characteristics, and can obtain extremely high peak light intensity with lower pulse energy. The emergence of ultra-short pulse chirp amplification technology has greatly improved the intensity of ultrafast green laser pointer. Unlike traditional long-pulse lasers…
Processing technology will usher in new and rapid development opportunities laser pointer
In the process of interaction between ultra-fast ultra-strong laser and matter, as the laser intensity continues to increase, various nonlinear effects continue to increase, and phenomena such as high-order harmonics, above-threshold ionization, tunneling ionization, etc. appear, and the cycle magnitude The ultra-short laser pulse loses the periodic characteristics of the wave phenomenon, leading to a…
Important technology of laser pointer that generates ultrashort pulses
The so-called Q-switching refers to the technology of adjusting the Q value of the laser. In the initial stage of laser pumping, the Q value of the resonator is adjusted to a very low level, so that the laser does not meet the oscillation conditions temporarily. When a high particle number density is obtained under…
The shortest pulse laser pointer that can be obtained under the experimental conditions
The Bragg mirror is composed of alternating Si02 and Ti02 coatings, and the refractive index of the coating changes stepwise. Such a structure introduces a negative dispersion relationship. The front of the mirror is like a transmission grating that produces partially reflected light, while the back of the mirror produces Bragg reflection. In order to…
