Paper Abstract

We use an algebraic method to derive explicit expressions for the structure of paraxial modes in a cavity consisting of astigmatic mirrors. The algebra is based upon the use of ladder operators that raise or lower the mode indices, when acting on a mode function. We show that the method is also applicable when the mirrors perform a uniform rotation about their axes. We also find expressions for the orbital angular momentum in these modes.
