The formation of dissipative solitons is influenced by various factors, such as spectral filtering effect and Kerr nonlinearity effect. This interaction leads to the possibility of mode locking on a large range of parameters, generating pulses with completely different types and evolution from conventional physical laws and optical properties, tolerating higher nonlinear effects, and effectively a...
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...
Femtosecond laser emits ultra short light pulses with a duration of less than 1 picosecond, reaching the femtosecond domain. The characteristics of femtosecond lasers are extremely short pulse width and high peak intensity.Ultra short blasting can minimize waste heat, ensure precise material processing, and minimize incidental damage. Their peak intensities can cause nonlinear optical interactions...
Recently, the Research Group of Nonlinear Photonics Technology and Applications in the State Key Laboratory of Transient Optics and Photonics Technology of Xi'an Institute of Optics and Fine Mechanics has made important progress in the field of super surface nonlinear photonics. Relevant research results were published in the internationally famous journal Nanoscale Horizons. The first author of t...
It is reported that researchers from BIAS Bremer Institution f ü r angewandte Strahltechnik GmbH in Germany have reported a comparative study of laser deep penetration welding processes for pure nickel using blue and infrared light wavelengths. The related research was published in Welding in the World under the title "Process comparison of laser deep penetration welding in pure nickel using blue ...
