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...

Laser gas analysis can achieve high sensitivity and selectivity in gas detection. The multi-component capability and wide dynamic range of this detection method help analyze gas mixtures with a wide concentration range. Due to the fact that this method does not require sample preparation or pre concentration, it is easy to adopt in the laboratory or industry.Gas analysis is crucial for determining...

Quantum optics is a complex field where theoretical and experimental physicists collaborate to achieve breakthroughs in explaining subatomic level phenomena.Recently, Farokh Mivehvar from the University of Innsbruck used the most comprehensive model in quantum optics, the Dicke model, to study the interaction between two groups of atoms in a quantized field. This new study makes it possible to obs...
