pulse length (m):
cavity round trip length (m):

Pulse is assumed to be transform limited Gaussian (TBP=0.44).
Temperature is from E=k_B T.
Round trip cavity length is in vacuum with FSR=relative frequency.

Fabry-Perot microcavity length

One resonance at wavelength lambda1, the next resonance one FSR away at lambda2. The FP cavity length (in vacuum, 2*round trip length) is calculated in micrometers.
