The deformable mirror used in adaptive optics can instantly correct the static wavefront aberrations and atmospheric turbulence wavefront disturbances of the optical system by changing its surface. This enables the optical system to automatically adapt to changes in the environment and maintain optimal performance. It is widely used in high-resolution astronomical observations, laser atmospheric t...
The femtosecond laser emits ultra short optical pulses with a duration of less than one picosecond, reaching the femtosecond level (1fs=10-15s). The characteristics of femtosecond laser are extremely short pulse width and high peak intensity.Ultra short pulse trains can minimize residual heat, ensure precise material processing, and minimize incidental damage. Its high peak intensity can induce no...
Researchers from the International Solar Research Center at Konstanz and Delft University of Technology have discovered a method to pattern the back end of a cross finger rear contact battery, improving its efficiency by making certain parts of the solar cell thicker.Researchers have developed a new technology that enhances oxidation in selected areas by patterning the back or back of IBC solar ce...
Pierre Agostini, Ferenc Krausz, and Anne L'Huillier won the award for their ultra short optical pulses, which made close research on electrons possible.Ferenc Klaus, Anne Lullier, and Pierre Agostini (from left to right)Image sources: BBVA Foundation, Kenneth Ruona/Lund University, Ohio State UniversityThis year's Nobel Prize in Physics was awarded to three physicists - Pierre Agostini of Ohio St...
Topological laser (TL) is an ideal light source for future new optoelectronic integrated chips, designed and manufactured using topological optics principles to obtain robust single-mode lasers. Electrically pumped topology lasers have become a research hotspot due to their small size and ease of integration, but topology lasers based on electrical injection are still in the early stages of resear...
