Self-pulsation

As is known spiking a generally undesirable effect which occurs during the transient phase of a laser. The laser sends it a chaotic result of strong, short light pulses, called spikes, from. The population inversion Previously established the laser builds even from so far that they can fall below the laser threshold again. Thus, the intensity of the laser radiation in the transient varies widely and irregularly. Since these spikes, however, have a very large power, they can be used eg for pulsed lasers.
