Two possible good configurations.

Code for creating these are found on our GitHub repo

Explaining the plot:

  • xaxes: Frequency detuning of laser wrt cavity
  • yaxis: Power transmitted through curved optic/ Incident power on cavity
  • Non-black lines labeled in the legend refer to m+n and the same line contains contribution of both the carrier and the first order phase modulation side-bands.
  • Dashed lines correspond to different (m,n) modes coloured so that all modes with same m+n have the same colour
  • Black line is the total power in all modes for the carrier and sidebands
  • Cavity finesse ~312 with input coupler transmission = 0.01
  • The frequencies written near the central peak are the separation from TEM00 of the closest two peaks
