9.4 The Fabry-Perot Resonator
9.4.1 The Fabry-Perot Resonator Was Ignored for too Long
It was the French physicists Boullouch and Fabry who, at the beginning of the twentieth century, discovered the fascinating optical properties of the arrangement of two facing parallel mirrors with excellent accuracy. For many years this arrangement was universally known as the Fabry-Perot (FP) resonator and was exclusively used for spectroscopic applications since it is a very dispersive and very luminous device. For a long time after that the FP resonator was considered as an electromagnetic resonator very analog with the resonant circuits used in radio or with microwave resonators. In Section 6.4 we have studied the FP resonator as a multiple wave interferential device, we are now going to use a new approach very near to radio and microwave methods.
9.4.2 Transient State of a Fabry-Perot Resonator
The FP resonator of Figure 9.22 is made of two planes and two parallel mirrors separated by a distance d. A planar monochromatic wave R 0, with its wave vector parallel to the axis of the FP resonator, arrives at mirror M 1 on which a transmitted wave R 1 and a reflected wave L 0 are generated. The wave R 1 propagates toward the right and arrives at the second mirror where a reflected wave L 1 and a transmitted wave R 2 are generated. There is no reason to introduce a wave L 2 since the half-space...
