The green and blue laser diode series provides higher beam quality

Detecting the presence of nanoscale plastic particles in the environment has become a topic of concern for industrial societies worldwide, not least since particles of that size can evade the body's blood-brain barrier and damage metabolic processes.Optical technologies have been at the forefront of these monitoring efforts. Recent examples have included the use of stimulated Raman scattering to s...

In the interaction between ultra short and ultra strong laser and matter, electrons with short pulse width and high energy are generated, commonly referred to as "hot electrons". The generation and transport of hot electrons is one of the important fundamental issues in high-energy density physics of lasers. Superhot electrons can excite a wide range of ultrafast electromagnetic radiation, as well...

Semiconductor laser pump sources, especially those with a wavelength of 969nm, have become the preferred choice for high-power/high peak energy disc lasers due to their reduced quantum losses and heat generation.The 3000W 969nm fiber coupled semiconductor laser system launched by BWT uses 800 μ m NA0.22 fiber to output flat top optical energy distribution, combining lightweight and excellent optic...

Researchers from Chalms University of Technology in Sweden have successfully improved the efficiency of optical microcombiners, making them a high-performance laser. This breakthrough will have a wide impact in fields such as space science and healthcare.The two rings in the figure are micro resonators, which play a crucial role in the implementation of efficient micro combs.The importance of micr...

Recently, a research team led by Professor Cai Wei and Professor Xu Jingjun from the School of Physical Sciences at Nankai University has experimentally confirmed for the first time the generation of polaritons, also known as Smith Purcell radiation, at the two-dimensional scale, and further demonstrated the ability of free electrons to regulate two-dimensional Smith Purcell radiation. The researc...
