Title: Method and apparatus for crystal growth
IPC: C30B15/02
Filed: 1960-01-19
Abstract: <PICT:0892088/III/1> A monocrystalline rod 48 of semi-conductor material, e.g. silicon or germanium, containing doping additives is pulled from a melt 20 contained in a crucible 18 which is supplied with doping material from an upper tube 60 and with semi-conductor material from a lower extension tube 22 of diameter narrower than that of the crucible.  The supplied semi-conductor material is in the form of a rod 24 which closely fits tube 22 and is melted at its upper end to form the melt 20 by means of an induction heating coil 14. Tube 22 slides over rod 24 under the action of gravity as melting proceeds, the relative downward movement being controlled by a pin 28 which prevents rod 24 from passing into crucible 18.  Rods 24 and 48 pass through packing members 40 and 46 respectively in an enclosure 16 adapted to provide a desired atmosphere around the melt.  Upward movement of rods 24 and 48 is effected by means of rollers 42 and 58 respectively.  Rod 24 may move upwards continuously at such a rate that the crucible is maintained stationary.  Alternatively, rod 24 may be intermittently moved rapidly upwards carrying the crucible 18 therewith from a position in which a stop 25 rests on the bottom of enclosure 16, the crucible thereafter being allowed to return to its original position under the action of gravity while the rod is stationary.

Title: Laser apparatus
IPC: H01S3/097
Filed: 1966-01-18
Abstract: 1,126,942 Lasers. CONTROL DATA CORP. 18 Jan., 1966 [18 Jan., 1965], No. 2389/66. Heading H1C. In a laser inelastic collisions between atoms are. caused to both enhance the upper lasing level and relax the lower lasing level by selecting the active medium such that the laser transition is partially forbidden by at least one electric dipole selection rule. By selecting the active media as above and indirectly exciting the upper level by collisions of the second kind with a more populous atomic species having an isolated level thus eliminating electron excitation of the lower level, the upper level being chosen to have a wave number less than 25,000 wa e numbers above the ground state a more efficient laser can be obtained. In one embodiment, Fig. 3 (not shown), a manganese-noble gas system may be employed, the upper levels being populated by inelastic collisions with the noble gas atoms in their ground state. In a further embodiment excitation is by means of inelastic collisions with lead the two lowest levels of which are employed. Since the elements having appropriate energy levels with low-lying levels have partially filled shells and tend to bond strong'y either to themselves or to other atoms temperatures higher than 1500 C. are required. The arrangement of Fig. 5 (not shown), employs an alumina tube (102) having sapphire windows (104), (106) arranged at Brewster's angle sealed to glass or quartz tubes (108), (110) which are in turn secured to the alumina tube by gas-tight seals (112). Pumping is by means of an R.F. discharge, the generator being connected to electrodes located near the ends of the alumina tube which discharge serves to raise the temperature of the manganese and lead in the tube (102) to the required high temperature. A noble gas buffer acts as a buffer between the hot innermost part of the alumina tube and the cooler windows (104), (106) and as a buffer for manganese vapour. Heat generated in the laser is conserved by means of a vacuum jacket and reflecting surface arranged around the tube. An optical cavity is formed by a concave reflector and a plane reflector. Provision may be made to recirculate the manganese after it has condensed. If the active medium is lanthanum or yttrium the operating temperature is 1800 C. and the apparatus used is as shown in Fig. 6. The tube in which laser action occurs, 202, is made of tantalum which is heated by a heater coil 218 or itself acts as the resistance element of a heater. The tantalum tube 102 also acts as the anode for a cross discharge, the cathode comprising a tungsten ribbon 204 having a narrow central portion and wider end portion. The windows of the apparatus may be arranged at Brewster's angle and mirrors are provided if oscillations rather than amplification is required.
