Abstract
Along an axis (2) of an optical cavity there are: a mirror (3) having a W-shaped cross section to give inner and outer conical reflecting surfaces (4, 6) which are oppositely inclined, a plane mirror (8) having an axial opening and facing the W-shaped mirror (3), a convex mirror (16) receiving the oscillating radiation from the W-shaped mirror (3) via the opening in the plane mirror (8), and a mirror (17) disposed between the plane mirror (8) and the convex mirror (16), said mirror (17) having an aperture and being inclined to the axis so as to extract laser energy from the oscillator.
