Figure: a. Schematic diagram of the HCF-LN-CPPLN experimental setup. W. CaF? Window M, mirror.b. The bright white light circular spots emitted by the CPPLN sample.c. The first-order diffraction beam of B displays a colorful rainbow pattern from purple to red.d. The HCF-LN-CPPLN module generates normalized spectra of the output full spectrum laser signal through the second NL HHG and third NL SPM e...
Recently, teachers and students from the Institute of Solid State Laser and Ultrafast Photonics at the School of Physics and Optoelectronic Engineering have made significant progress in the study of ultrafast carrier dynamics in optoelectronic functional crystals. The related research results are titled "Anisotropic carrier dynamics and laser fabricated luminosity patterns on oriented single cryst...
Laser coding and marking technology expert DataLase has launched a series of new colorless to white coatings for a range of packaging applications.These coatings are centered around biodegradable and sustainably sourced raw materials, providing high contrast white printing even on difficult substrates such as 12 micron PET and shrink film, under the weight of flexographic and gravure coatings. Thi...
When scientists discovered that laser pulses can rapidly cause refractive index changes in the medium, resulting in "photonic time crystals (PTC)" in the near-visible light band, the door to a disruptive new application in optics seemed to quietly open.Scientists have a certain degree of understanding of photonic crystals and time crystals, the two have almost nothing in common, the basic common p...
Recently, in order to improve the National Aeronautics and Space Administration (NASA) space communications capabilities, NASA plans to send a technology demonstration called "Integrated LCRD Low Earth Orbit User Modem and Amplifier Terminal (ILLUMA-T)" to the space station in 2023.ILLUMA-T and the Laser Communications Relay Demonstration (LCRD), launched in December 2021, will together comp...
