Abstract
Previous work by the authors on the effects of slow spatial cross relaxation is extended in two directions. First, off-axis modes are included in the calculations, and thus it becomes possible to calculate the number of oscillating off-axis modes as a function of the various laser parameters. In this way the expected beam angle of a laser can be predicted. Second, a more detailed analysis of the spiking behavior is given; both regular and irregular spiking trains may be obtained depending upon the laser parameters and the pump power.
