Radiation Effects on 780 nm Space AOM Series and Mitigation Strategies
Space environments expose optical components to a spectrum of ionizing radiation—protons, electrons, heavy ions, and cosmic rays. For 780 nm Acousto-Optic Modulators (AOMs), radiation can degrade crystal quality, induce absorption bands, and impair acoustic transducer performance. Understanding and mitigating these effects is vital for long-duration missions beyond low-Earth orbit, such...

Ultra-narrow linewidth single-frequency fiber lasers (<1 kHz) are critical for applications like coherent optical communications, gravitational wave detection, and high-precision metrology. However, thermal noise in the fiber Bragg grating (FBG) and gain medium introduces phase fluctuations, ultimately limiting the achievable linewidth.
