Application of a ruby laser to high-speed photography

Abstract

Multiple pulsing of a ruby laser has been achieved and incorporated into a high-speed camera. The pulsing is accomplished by means of cavity Q spoiling techniques utilizing a Kerr cell. a rotating mirror camera is used with the laser acting as a stroboscopic light source to record the events. Framing rates of over a million frames per second with exposure times of less than 30 nsec are easily obtainable. This in conjunction with the highly intense monochromatic, cohere and collimated nature of the laser light makes the high-speed laser camera desirable in many areas of research.
