Alignment-insensitive resonators using focusing corner cubes
Abstract
A corner cube constructed using three long radius spherical mirrors has been found to correct for astigmatism and can produce diffraction limited focused retroreflected light. Laser resonators using focusing corner cubes exhibit alignment insensitivity and an ability to track a wandering gain medium. These are both very desirable properties for long FEL lasers. A computer analysis of various types of misalignments is presented.
