Ultrafast lasers for chemical and physical processing of graphene

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 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 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…

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…
