摘要	1,113,920. Semi-conductor lasers. STANDARD TELEPHONES & CABLES Ltd. 18 April, 1967, No. 17767/67. Headings H1C and H1K. A laser unit comprises a semi-conductor laser die in a sealed chamber. A gallium arsenide laser die 4 is held between raised sections 2 of copper members 1 coated with layers of indium 3 and a glass hollow member 5 completely surrounds the die and is sealed to the members 1 by means of indium washers 6. The members 1 are normally cylindrical in crosssection but may be square or rectangular. Similarly the transparent member 5 and washers 6 may be cylindrical, hollow, square or hollow rectangular. The various parts of the unit are pressure welded together. The laser unit may be packed into closely packed arrays.
