Cinemas are in a developmental stage. Their roles are changing and the rules are being rewritten. Many people have proposed a way to make cinemas a truly unique place by providing audiences with a higher quality experience. It is along this route that UCI Cinemas continues to move forward. In recent days, it has officially launched a 4K laser projector and had a special date with the new MCU movie...
Recently, the team led by Professor Lv Zhiwei and Professor Bai Zhenxu from Hebei University of Technology, in collaboration with Professor Richard Mildren from Macquarie University in Australia and Professor Takashige Omatsu from Chiba University in Japan, successfully achieved direct output of Raman vortex optical rotation with large wavelength extension in a diamond Raman laser oscillator. This...
In a groundbreaking scientific study published in Volume 13 of the Scientific Report, researchers reported on the results of Young's double slit interference experiment using oscillating vortex radiation under a photon counting system. The experiment involves using a spiral oscillator to emit second harmonic radiation in the ultraviolet range. Using an ultra narrow bandpass filter in the low curre...
Recently, the Cold Molecular Ion Research Group of the Institute of Precision Measurement has made significant progress in the loading, trapping, and recognition of thorium ions. The related research results have been published as cover and selected articles in the international physics journal Journal of Applied Physics, titled "Loading and identifying variable charged thorium ions in a linear io...
Laser sources operating in the 1.2 μm band have some unique applications in photodynamic therapy, biomedical diagnostics, and oxygen sensing. In addition, they can be used as pump sources for mid-infrared optical parameter generation and visible light generation through frequency doubling.Laser generation in the 1.2 μm band has been achieved by different solid-state lasers, including semicon...
