ABSTRACT:
A laser apparatus includes two sets of pumping arrangements for providing pumping energy for a laser medium used in common, each comprising a reflector with a reflective surface which defines an elliptical cavity and a pumping source located along a focal line of the ellipse formed by the elliptical cavity. One pumping arrangement is usually used and the other is held in reserve as a spare. When the former is out of order, the latter is automatically made available.
