The Advantages and Disadvantages of Passive vs Active Q-Switching

Q-switching is the most effective method for producing high energy pulsed lasers.  While there are many different varieties of a q-switch, they all follow the same basic operating principle.  Q-switches temporarily increase the cavity losses so that the gain threshold is artificially high preventing the laser from emitting light.  This process allows the population inversion inside of the gain medium to grow until it becomes fully sa… Read More
