The General Quantum Limit for and the Optimization of the Minimum Measurable Frequency Shift in a Laser
Selim M. Shahriar, Ruoxi Zhu, Jinyang Li +7
We show that, contrary to conventional understanding, the minimum measurable frequency shift (MMFS) for a single-mode ideal laser is determined by a combination of phase diffusion…
