Abstract : A laser system has been devised which provides a preselected number of laser bursts at controlled intervels, by shaping the output of the optical pump light in a suitable manner. Two techniques were used. A system was constructed to demonstrate the principle. The working model provides up to three 15 microsecond laser bursts per firing, while the time between bursts is controlled by preselected delays of from 50 to 500 microseconds. The peak power output is several kilowatts. Although the model employs a 2'' x 1/4'' Neodymium-doped glass laser, the method is applicable to a wide variety of laser materials and sizes. (Author)
