Abstract

1,181,021. Lasers. AMERICAN OPTICAL CORP. 9 Feb., 1967 [31 March, 1966], No. 6250/67. Heading H1C. In a laser structure a doped glass active medium rod is disposed within a main body of glass provided with a bore parallel to the rod and filled with an ionizable gas forming the pumping source. The plan view of Fig. 1, shows a cylindrical elongated glass member 12 and a laser rod or fibre 14 of trivalent neodymiumdoped barium crown glass, an erbium-ytterbium-neodymium doped laser glass or an ytterbium-neodymium doped laser glass, extending therethrough. The refractive indices of member 12 and rod 14 are such as to form a substantially zero refractive index difference therebetween. A polished bore 16 running parallel to the laser rod 14 is filled with xenon, argon or helium which gas or gases are pulsed by sealed electrodes 20, 22. The laser optical cavity is formed by coatings 25, 27 or separate mirrors may be employed. In order to reflect the pumping light on to the laser rod the external surface of the glass body 12 is coated with a first layer 30 of silver and on the outer surface of this coating is deposited a copper coating 32 which latter coating dissipates heat produced during operation. In the arrangement of Fig. 3, the main body 12<SP>1</SP> is elliptical in shape with the laser rod or fibre 14<SP>1</SP> positioned at one face and the flash tube chamber at the other. Further cooling is provided in this arrangement by a plurality of radially extending cooling fins 38 running lengthwise or transversely of the structure, and a further jacket 42 encloses the whole structure and through which a coolant fluid may be pumped. The laser rod or fibre may in an alternative arrangement be provided with a doped glass cladding prior to insertion in the structure, Fig. 4 (not shown). The laser may operate as a generator or amplifier.
