It is acquired by an Advantest Q8347 optical spectrum analyzer with a resolution of 0.9 GHz and a frequency span range of 200 GHz over a center frequency of 384.7796 THz. When the stabilization setup is not working, the output spectrum of EOCG is nearly the same as the single mode spectrum of seed laser. Occasionally, an asymmetrical comb spectrum is generated with very short duration.
