Abstract
1,135,988. Lasers. NATIONAL RESEARCH DEVELOPMENT CORP. 2 Nov., 1967 [22 Oct., 1966], No. 47476/66. Heading H1C. A semi-conductor laser diode pumped both by direct current injection and by directing a beam of electrons on to the surface, is modulated by varying the intensity of the electron beam incident upon the surface. In Fig. 3 the current J through region A 1 is maintained at about the threshold for lasing, so that the electron beam incident upon region A 2 causes laser action. The electron beam may either be intensity modulated or may be deflected to either side of the laser in order to modulate the laser output. A klystron or travelling wave tube may be built around the electron beam to cause bunching of the electrons.
