Aio Optics Introduces SpectrumShaper-R4 Spectral Broadening Module
Aio Optics has introduced the SpectrumShaper-R4 series spectral broadening module, extending the broadening range from 1-30 GHz to 1-80 GHz. An integrated single-frequency seed source is available as an option, and the built-in spectral profiles and software interaction have been optimized. Aimed at high-power narrow-linewidth fiber lasers, the module controls the seed spectrum through electro-optic phase modulation of an RF signal to suppress nonlinear effects during amplification.
Why we recommend it: Changes in the broadening range and integrated seed-source options correspond to specific design requirements for narrow-linewidth fiber lasers, useful for comparing trade-offs between spectral control and full-system integration.
