I am trying to understand the conditions for an optical resonator with unsymmetric reflectors, i.e. the focal lengths of the two reflectors are different. According to wikipedia (http://en.wikipedia.org/wiki/Optical_cavity#Stability) 0 < (1 - L/R1)(1 - L/R2) < 1 is the equation that will guarantee stability and they say that this can be derived from ray matrix transfer analysis but when I try to do it (I'm assuming it's an eigenvalue problem) I keep getting these long intricate conditions that don't at all resemble this simple result.
1) Are there any conditions on the system that need to be put in?
2) is there anywhere that goes through this derivation step by step?
TIA
Edit: Sorry I didnt capitalize the thread title, I noticed it after I posted and can't seem to change it
