摘要: Selective optical resonator comprising at least two mirrors and a selective means disposed between two of these mirrors, said means being constituted by:an at least partial linear polarization means for the light in a direction P,a first birefringent plate having two neutral lines, one forming an angle .alpha..sub.1 =0 with direction P,an optically active substance having a birefringence with dispersion and which rotates the light polarization direction by an angle .theta. dependent on the wavelength of the .lambda. light,a second plate which is identical to the first having two neutral lines, one forming the angle .alpha..sub.2 =.theta. with the direction P, whereby the resonator is then selective for said wavelength .lambda..
