Today, VCSELs (vertical cavity surface-emitting lasers) are used in everything from computer mice to face-scanning hardware in smart phones. They are renowned for their ability to integrate seamlessly into semiconductor chips, VCSELs are still considered to be an active field of research, and many researchers believe there are still important applications waiting to be discovered.The laboratory of...
Recently, Vector Photonics, a well-known surface coupled laser technology supplier in the UK, announced that the company has received £ 3 million in financing (including £ 1.667 million in equity investment and £ 1.27 million in additional research funding, equivalent to approximately RMB 27.63 million) to help commercialize its surface coupled laser technology.(Image source: Vector Photonics)Vect...
A mode-locked laser is an advanced laser that can generate very short optical pulses with durations ranging from femtoseconds to picoseconds. These lasers are widely used for studying ultrafast and nonlinear optical phenomena, but they have also been proven to be applicable to various technological applications.Researchers at the California Institute of Technology have recently been exploring the ...
Laser cladding technology, also known as laser additive manufacturing technology, uses high-energy laser as the heat source and metal alloy powder as the cladding material. Through the synchronous action of laser and alloy powder on the metal surface, it quickly melts to form a molten pool, and rapidly solidifies to form a dense, uniform, and controllable thickness metallurgical bonding layer, the...
Photoacoustic tomography (PAT) is a novel hybrid medical imaging technique that enables precise imaging of biological tissue structures at different spatial scales. It has been widely used in various fields, including brain imaging, cancer detection, and cardiovascular disease diagnosis. However, due to limitations in data acquisition conditions, photoacoustic tomography systems typically can only...
