Abstract

The active medium of a laser consists of yttrium aluminium garnet (Y3, Al5O12) containing from one-half to 10 atomic per cent of 3+ neodymium ions based on the number of yttrium atoms, a preferred concentration being between 1 and 6 atomic per cent. A construction is shown in which a yttrium aluminium garnet rod 2 and a quartz-iodine tungsten lamp 3 are located at respective focii of an elliptical reflector 1, the arrangement generating either a continuous or pulsed optical output 6. The ends of the rod are plane parallel and coated in the usual manner to form an optical cavity. Operation may be at room temperature, or at a lower temperature if narrowing of the line width is required. The active medium may also serve as an amplifier of optical radiation, Fig. 2 (not shown).
