The recent definitions of coherencetime and coherence length are introduced.
综述了目前对相干时间、干长度的各种定义。

The power density spectrum of an inner-phase-modulated optical fiber resonator is analyzed theoretically and experimentally, which is valid for any source coherencetime.
If you start screwing around with the event you can lose coherence pretty easily - for example by forcing everyone to go together at a random time to hear a sponsor pitch.
