title: Spiking emission from many-element lasers.
abstract: Experimental results on the time behavior of the light emission from many-element lasers (MEL) are reported for both Fabry-Perot and confocal geometry. Very regular relaxation oscillations can be easily obtained from the MEL in a number of working conditions. In the case of Fabry-Perot geometry a timeresolved analysis of the spectral output, near- and far-field patterns have been carried out in order to correlate the regular spiking behavior with the number of active modes present. The regular spiking from an MEL seems to be characteristic of single-mode operation.
