ABSTRACT:
Apparatus configured to minimize wavefront distortion of a coherent light beam is disclosed. The lasing medium of the laser apparatus has a hexagonal cross section and an internal surface with a circular cross section coaxial with a longitudinal axis of the lasing medium. The internal surface defines an interior space for receiving an optical pumping source. The external faces of the lasing medium are surrounded with a circumferential reflector and fluid coolant is flowed over the internal surface and external faces. The coherent light beam is passed through the lasing medium to follow a helical course totally internally reflecting off of the external faces.
