Recently, scientists from France, Qatar, Russia, and Greece have published a paper in the latest issue of Nature Communications. According to the paper, in the previous attempt to write ultra-fast lasers in silicon, the problem that femtosecond lasers cannot structurally process bulk silicon has been broken. The use of extreme NA values allows laser pointer pulses to…

Laser-driven Proton Knife Will Treat Cancer
Recently, the results of a study on laser treatment of tumors were published in the Physical Review Letters. Specific research claims that the theory that collision-free acceleration mechanism can be used to generate such a high-quality and high-energy proton beam is achieved by calibrating the proton energy to 100 mega-electron volts under the existing laser pointer conditions…
Chinese Aircraft Carrier Is About To Be Equipped With Laser
If maritime laser weapons are used as a near-defense system, then maritime laser weapons have great promise. Everyone knows that China’s laser pointer weapon is one of the best in the world today. The United States has spent fifteen years tackling key problems. Just to break through China’s technological blockade is the best affirmation of Chinese laser…
Laser Marking Escorts New Deal For Pesticide Labels
For pesticide products, packaging and labeling are like faces and carriers of pesticide product information. However, for many years now, pesticide labeling problems have been prominent: operators have privately expanded the scope of registered crops (objects to be controlled) and laser pointer, prominent brand names, and weakened Irregularities such as generic names, labels, and exaggerated slogans…
Laser Beam Technology Brings Hope For Ultra-high Speed
A new method of implementing an “unbreakable” quantum cryptosystem can transmit information at a rate more than 10 times faster than previous experiments. Researchers have developed a new method that overcomes a major problem in the implementation of quantum cryptosystems, which improves the prospect of implementing a usable “unbreakable” method for sending hidden light in laser…
Targeted Interventions Laser Pointer
A postdoctoral researcher at the ETH Zurich research group used the device to generate the shortest laser pulses in the world. Generally in the movement of atoms and molecules, scientists are able to study all movements of atoms and molecules in their basic time range. The range of molecular rotation is on the order of…
Future Development Of High-power Semiconductor Processing
With the development of semiconductor laser chip technology and integrated technology, the power of high-power semiconductor lasers is getting higher and higher, and the laser pointer beam quality has also improved year by year. The power of high-power semiconductor lasers currently used in laser manufacturing can reach 6000W or higher. The light beam can be coupled into…
High Power Semiconductor Laser Application Advantages
A semiconductor laser is a laser that uses a semiconductor material as a working medium. This laser pointer has the characteristics of small size, light weight, long life, simple structure and ruggedness. With the development of industry, the laser power of semiconductor lasers has climbed to the kilowatt level, and has applications in laser brazing, laser cladding,…
Welded Appearance Is Smoother Laser Pointer
Laser cutting improves efficiency. In the home appliance industry, argon arc welding or fiber welding is traditionally used, but the traditional welding process has a poor appearance and brings great difficulty to the next process. The laser pointer welding has a smooth appearance and small thermal deformation. Save material, simple grinding or polishing after welding can complete…
Laser Technology Helps Upgrade Home Appliances
In recent years, China’s home appliance industry has carried out a series of reforms and innovations around transformation and upgrading. In 2015, the industry further deepened the pace of transformation and upgrading, with remarkable achievements in the transformation of various factories and model innovations, rapid development of channel construction, and the trend of upgrading the…
