Abstract
A laser resonant cavity for utilizing media, having an annular cross sect as well as two end mirrors. The end mirrors exhibit a toroidal surface, and at least one end mirror has at least one aperture through which the laser beam can be coupled out.
Claims14
A laser cavity for laser media, comprising a first annular end mirror;
- and a second annular end mirror facing said first annular end mirror to define the laser cavity, each of the end mirrors having a concave reflecting surface facing the other one of the end mirrors, at least one end mirror having an aperture therethrough out of which the laser beam can be coupled.
A laser cavity for laser media, comprising a first annular end mirror having a concave reflecting surface defined by a toroidal surface;
- a second annular end mirror having a planar reflecting surface facing the concave reflecting surface of said first annular end mirror to define the laser cavity, said second end mirror having an aperture therethrough out of which the laser beam can be coupled.
