ABSTRACT:
A laser including a resonant cavity having a solid amplifier medium (1, 7, 8), an inlet mirror (2, 9, 10), an outlet mirror (3, 11, 12, 21), and an optical pumping device (5, 13, 16) to emit at least one pumping beam from the amplifier medium. The laser is operable to vary the direction of the pumping beam in the amplifier medium, and the cavity possesses a geometry enabling a laser beam to be generated, irrespective of the direction of the pumping beam.
