3. Resonator optics

Optical Resonators

Resonator features

  • Energy storage - spectral filtering
  • Resonator modes and mode density

Plane mirror resonators

  • Resonator modes
  • Axial resonances
  • Cavity losses and their figure of merit (fractional loss, cavity photon lifetime, Q-factor, finesse)

Spherical mirror resonators

  • Resonator modes
  • Axial and transverse resonances
  • Stability condition
  • Diffraction losses
