High-efficiency hollow-core optical fiber cable for medical procedures

A research group led by Prof. Jiang Haihe from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has designed a 6-hole microstructure anti-resonant air-core fiber (AR-HCF) with a larger core diameter of 78 μm.

Traditional medical laser devices often face challenges such as complex structures and low efficiency. The AR-HCF overcomes these problems with its simple design, high transmission efficiency, and flexibility.

This innovation enables efficient transmission of high-energy pulsed lasers, particularly in the mid-infrared range, which is critical for medical procedures.

National Science Day is observed on the day Indian Physicist Chandrasekhara Venkata Raman discovered the Raman Effect. The Raman Effect is the phenomenon where light gets scattered when passed through a transparent material, leading to changes in wavelength and energy. In 1928, on February 28, CV Raman discovered the Raman Effect. He also received the Nobel Prize in Physics in 1930 due to his significant contribution in the field of Physics. Commemorating the discovery, National Science Day is observed on February 28 every year.
