Ultrafast lasers (picoseconds and femtoseconds) are widely used in thin film patterning in the development and manufacturing of micro-nanoelectronic devices including photovoltaics, displays, sensors, or large organic electronic devices. The main advantage of the ultrafast laser pointer is its limited thermal effect and fast energy dissipation, so as to realize the patterning of complex multi-layer ultra-thin films….

Ultrafast pulse lasers increase data transmission speed
According to a recent report by the “Physicists Organization Network”, the ultrafast pulsed laser pointer developed by the Korea Institute of Science and Technology (KIST) produces a frequency 10,000 times higher than the current state-of-the-art pulsed laser. This is achieved by inserting an additional resonator containing graphene into a fiber pulse laser oscillator operating in the femtosecond…
The rapid development of laser light source technology in the Chinese market
The advantages of laser are not only technical, but also have strategic significance for the development of the country’s entire imaging industry. The development of laser pointer light source technology in the Chinese market is very fast, and the gap between technology and foreign countries is not particularly large. In the past, projection light sources have been…
The project attempts to use the development of integrated laser pointer photonics
Through the MOABB project, DARPA researchers are committed to building a plane millimeter-level transmitter/receiver unit with a high fill factor aperture, non-mechanical beam control, and integrated amplification. DARPA scientists claim that free-space optical systems have huge potential for sensing, lighting, and communication. Micron wavelengths can achieve an angular resolution of 0.001 degrees. The MOABB project…
It is expected to be used to realize highly flexible and compact laser pointers
The practical applications of this technology include all-optical reconfigurable routers, ultra-fast optical modulators and optical switches for optical networks, and microwave photonic circuits. What is needed now is to develop these ideas into practical applications as soon as possible. In an interview with reporters, the project leader, professor of physics and astronomy at the University…
The development trend will give birth to a larger-scale laser pointer industry
Until 2016 and 2017, when laser pointer suddenly entered the market, the price of fiber lasers began to plummet. At present, it is basically in line with the trend of roughly halving prices every 18 months. In other words, the laser industry driven by fiber lasers will enter a period of rapid expansion similar to the development…
The quality and quantity of high-power fiber laser pointer products
In recent years, high-power fiber laser products have made remarkable progress in “quantity”. According to the “laser pointer Industry Development Report”, the shipment of fiber lasers above 1500 watts accounted for approximately 34.5% of the total shipments in 2018. It is expected that the shipments of high-power lasers in 2019 will exceed imported lasers. However, it…
Typical examples of high-power fiber laser pointer applications
Recently, the application of fiber laser welding technology in shipbuilding and automobile manufacturing has received considerable attention internationally. In developed countries in Europe and the United States, about 50%-70% of auto parts have used laser pointer processing technology, and laser welding and laser cutting are mainly used. Automobile manufacturers such as Shanghai Volkswagen also use laser processing…
South Korean researchers develop new laser pointer device to prevent food poisoning
As the number of food poisoning cases has gradually increased, South Korea has begun to implement relevant measures. It is understood that Korean scientists have developed a laser pointer to find bacteria on the surface of food. Researchers at the Korean Academy of Advanced Sciences have developed a red laser beam that is scattered on the surface…
A specific case of single-mode laser pointer application
The same multimode YLS laser is used for high and low brightness applications, such as welding, drilling, and precision cutting-an unprecedented capability. The high brightness allows the use of telephoto processing lenses, which are used to greatly improve the depth of field and minimize the damage to the optical components. Although high-brightness multi-mode laser pointer dominate the…
