Spiking (effect)
As spiking is called a generally undesirable effect during the transient phase of a laser occurs. The laser sends out a chaotic sequence of strong, short light pulses, so-called spikes. In doing so, the laser breaks down the population inversion that has previously built up to such an extent that it can drop below the laser threshold again . As a result, the intensity of the laser radiation fluctuates strongly and irregularly during the transient process. However, since these spikes have a very high performance, they can be used, for. B. be used in pulsed lasers .
