Expanding our scientific understanding often boils down to observing what is happening as closely as possible. Now, researchers from Japan have observed the nanoscale behavior of azo polymer films and triggered them with lasers.In a study published in Nano Express last month, researchers at Osaka University used a combination of cutting-edge scanning high-speed atomic force microscopy and optical ...
Recently, HüBNER Photonics, the leading manufacturer of high-performance lasers, has launched the latest member of the VALO femtosecond series - VALO Tidal. This laser not only represents a major leap in the fields of imaging, detection, and analysis, but also demonstrates the infinite possibilities of laser technology with its outstanding performance.The VALO Tidal femtosecond laser typically sho...
Laser processing is a relatively emerging non-contact processing method that utilizes the high energy of a beam of light to interact with materials and instantly vaporize or change their properties to achieve the expected manufacturing effect. It has gradually been promoted and applied in China in the past 20 years. Due to the different types, pulse widths, and wavelengths of laser generators, the...
High power optical frequency combs play a crucial role in nonlinear precision spectroscopy, extreme ultraviolet optical frequency comb generation, nuclear atomic clock research, and other fields. Fiber optic femtosecond lasers are the preferred solution for achieving high power optical frequency combs due to their simple structure, stable performance, and easy amplification. However, due to the un...
A group of researchers from the Max Planck Institute of Optoelectronics has made a significant breakthrough in using laser cooling to travel sound waves. This development brings us one step closer to the quantum ground state of sound in waveguides, which is of great significance for quantum communication systems and future quantum technology.By using laser cooling, scientists can significantly red...
