Curved Mirror Cavity — Radial Modes

Demonstration of multiple beam interference in transmission using a cavity with curved mirrors and a single-frequency laser light source

Observation of the intensity distribution associated with a variety of radial (or transverse) modes as a function of cavity tuning

Observation of the cavity transmission associated with radial modes as a function of cavity tuning

Demonstration of the properties of a confocal resonator, i.e., where the radius of curvature of each mirror is equal to the mirror separation

Demonstration of the behavior just below and just above the confocal condition
