Researchers from Bayreuth University and Konstanz University are developing new methods to control ultra short laser emission using soliton physics and two pulse combs in a single laser. This method has the potential to greatly accelerate and simplify laser applications.Traditionally, the pulse interval of lasers is set by dividing each pulse into two pulses and delaying them at different, mechani...
Image source: Federal Institute of Technology in Lausanne, SwitzerlandScience and Technology Daily, Beijing, September 27th (Reporter Zhang Jiaxin) Commercial femtosecond lasers are manufactured by placing optical components and their mounting bases on a substrate, which requires strict alignment of optical components. So, is it possible to manufacture femtosecond lasers entirely from glas...
Physicists from the University of Heriot and the University of Cambridge have developed an innovative laser system called Astrocomb, which can significantly improve the detection of exoplanets. This advanced tool can accurately measure the spectra emitted by nearby stars, which fluctuate due to the gravitational influence of orbiting planets. It is expected that this technology will enhance resear...
The rapid development of photonic integrated circuits (PICs) has combined multiple optical devices and functions on a single chip, completely changing optical communication and computing systems.For decades, silicon-based PICs have dominated the field due to their cost-effectiveness and integration with existing semiconductor manufacturing technologies, despite their limitations in electro-optic ...
Water is a natural resource that human beings depend on for survival and is used in many fields. In recent years, the patterning and flow control of trace water have attracted wide attention in materials science, chemistry, biomedicine and other fields."Draw the knife to cut off the water more flow"? No, it's "Laser cut water pattern"! On September 1, the reporter learned that Xi 'an Jiaotong Univ...
