Abstract

1,147,377. Lasers. AMERICAN OPTICAL CORP. 4 Nov., 1966 [2 Dec., 1965], No. 49616/66. Heading H1C. Laser light at 1À06 microns is generated in an active medium consisting of a glass host material activated with trivalent ytterbium and trivalent neodymium ions, the material being subjected to pumping energy so that the energy absorbed by the neodymium ions is transferred non-radiatively to the ytterbium ions to establish a population inversion therein, so that light at 1À06 microns is propagated from the stimulated emission of the trivalent ytterbium ions. The glass may contain up to 25% by weight of Nd 2 O 3 , preferably 5%, and up to 25% by weight of Yb 2 O 3 , preferably either 2 or 5%. It is stated in the Specification that it is known that glass containing Nd<SP>3+</SP> and Yb<SP>3+</SP> at 77‹ K. will produce stimulated emission at 1À06 microns from the Nd<SP>3+</SP> ions and at 1À015 microns from the Yb<SP>3+</SP> ions. It is further stated that at room temperature the terminal level for the 1À015 micron radiation is thermally populated so that emission at 1À06 microns from the Yb<SP>3+</SP> ions becomes dominant.
