Homework Help: Resonance frequency of confocal resonator

  1. Apr 4, 2012 #1
    1. The problem statement, all variables and given/known data
    A symmetrical confocal resonator has a length d=30cm, and the medium has refractive index n=1. Determine the frequency spacing [itex]\nu[/itex]F and the displacement frequency ([itex]\Delta\varsigma[/itex]/[itex]\pi[/itex])[itex]\nu[/itex]F. Determine all the resonance frequencies that lie within the band 5*1014[itex]\pm[/itex]2*109Hz. [itex]\Delta\varsigma[/itex]= [itex]\varsigma[/itex](z1)-[itex]\varsigma[/itex](z2) where z1 and z2 are the position of the mirrors

    2. Relevant equations

    3. The attempt at a solution
    I can only find the resonance frequency. How can I get the phase shift [itex]\Delta\varsigma[/itex] from the length of the resonator?
