A High Speed Optical Shutter for Forming a Laser Emission Pulse (Bystrodeistvuyushchii Opticheskii Zatvor Dlya Formirovaniya Impulsa Izlucheniya Opticheskogo Kvantovogo Generatora)

摘要

The paper reports on studies on the spatial uniformity and time characteristics of the Kerr cell. It analyzes the optimal construction and electrical parameters of a Kerr cell designed to form light pulses with minimal rise time. The analysis shows it is possible to build a shutter giving a series of light pulses of approximately 10 to the - 11th power sec duration. A Kerr cell with which a light monopulse of 0.4-nsec duration can be obtained is described. Ruby laser light of such duration was used in a design for seven-frame shadow photography of high-speed processes. (Author)
