Reducing stray light is one of the main challenges in combustion experiments using laser beams (such as Raman spectroscopy) for detection. By using a combination of ultrafast laser pulses and gated ICCD or emICCD cameras, a time filter can be effectively used to remove bright and constant flame backgrounds. When the signal reaches the detector, these cameras can open electronic shutters within the...

With the help of on-chip accelerator technology, researchers at Stanford University are getting closer to manufacturing a miniature electron accelerator that can have various applications in industrial, medical, and physical research.Scientists have proven that silicon dielectric laser accelerators can now be used to accelerate and limit electrons, thereby producing concentrated high-energy electr...

Recently, a research team from the School of Physics and Optoelectronic Engineering at Jinan University has elucidated for the first time the time-dependent quantum mechanism of two-photon absorption and proposed a two-photon absorption (fpTPA) optical nanoprinting technology based on few photon irradiation, successfully breaking through the bottleneck of traditional two-photon printing technology...

Researchers at King Abdullah University of Science and Technology (KAUST) in Saudi Arabia have found that laser scribing or creating nanodots on battery electrodes can improve their storage capacity and stability. The method can be applied to an alternative electrode material called MXene.Lithium-ion batteries have multiple drawbacks in a wide range of applications, and researchers around ...
