Comb-rooted multi-channel synthesis of ultra-narrow optical frequencies of few Hz linewidth
Heesuk Jang, Byung Soo Kim, Byung Jae Chun +5
We report a multi-channel optical frequency synthesizer developed to generate extremely stable continuous wave lasers directly out of the optical comb of an Er-doped fiber oscillat…
