Linewidth of laser

NettetFWHM of the photo-current power spectrum for a 1.3 gm DFB laser in different drive configurations. Without the filter (diamond symbols), but with the battery supply on, the linewidth levels out at 2 MHz. The solid circles are for the case of using the supply in AC mode but with the filter. The minimum linewidth in this case is about 715 kHz. NettetLocking the laser to the resonator led to a noise reduction of more than three orders of magnitude up to about 10 kHz, with an overall correction bandwidth of about 200 kHz. We achieved an overall linewidth reduction down to about 200 kHz over 1 s, about a factor of ten with respect to the unlocked case.
