Within the last few years there has been a revival of interest in the           dynamical behavior of laser oscillators.  From a purely scientific              standpoint, some fundamental laser transient phenomena which were once          known only to theoreticians are now observable in the laboratory.  From         a more practical point of view, many lasers of great commercial utility         are found to exhibit pulsations of known or unknown origin, and for             applications such effects may be either detrimental or highly useful.           The general purpose of this research is to search out additional                spontaneously pulsing lasers and to seek a better understanding of              those that are already known.  This research includes both experimental         and theoretical studies to extend the present state of knowledge                concerning such lasers.  Of special interest is a recently recognized           laser instability which causes deep modulation pulsations at MHz rates          in single-mode xenon lasers.  This instability is believed to be                responsible for important transient effects in helium-neon lasers and           probably other lasers as well.
