Ultrafast pulse lasers increase data transmission speed

According to reports, the ultrafast pulsed laser developed by the Korea Institute of Science and Technology produces a frequency 10,000 times higher than the current most advanced pulsed laser pointer. This is achieved by inserting an additional resonator containing graphene into a fiber pulse laser oscillator operating in the femtosecond range. The application of this method…

What is the status of high-energy laser weapons in India

According to reports, starting from April 2020, relevant foreign troops have violated the agreement between the two countries by building temporary bridges and building roads when arriving at the border, frequently crossing the border to fight for control, trying to unilaterally change the status quo of border control, leading to a sudden increase in the…

Directed energy laser pointer weapons are very important today

Both types of DEW are fatal to the human body and may cause burns or blindness. At the same time, this weapon can also destroy missiles, ships, unmanned aerial vehicles and equipment circuits deployed on the battlefield. As a key factor in future non-contact warfare, the potential applications of this technology will be used in…

Laser cutting quickly replaced many traditions

Steel pipes are used in all walks of life. Metal pipes are widely used in different industries. General pipes are usually 10 meters or even 20 meters long before they are formed. After being distributed to various industries, they need to be processed into parts of different shapes and sizes to meet the needs of…

Free space optical communication uses the light of a laser pointer to communicate

Through the MOABB project, DARPA researchers are committed to building a planar millimeter-level transmitter/receiver unit with high fill factor aperture, non-mechanical beam control, and integrated amplification. DARPA scientists claim that free-space optical systems have great potential in sensing, lighting, and communication. Micron wavelengths can achieve an angular resolution of 0.001 degrees. The MOABB project attempts…

Air Force develops chip-level lidar sensor for 3D mapping

According to reports, researchers from the California-based company are developing chip-level, lightweight, economical LiDAR (LiDAR) sensors for military 3D laser pointer mapping, vegetation penetration photoelectric sensing, navigation and long-range communications. Officials of the US Air Force Research Laboratory at Wright-Patterson Air Force Base in Ohio recently announced a $8.2 million contract with the company to develop chip-level…

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….
