WebLaser Pulse Generation 36 Passive Mode Locking In a passively mode-locked laser, the loss modulation is done by a saturable absorber, such as a SESAM (p. 50). This mechanism allows us to generate shorter pulses than with active mode locking. The reason is that the shorter the circulating pulses become, the faster the loss modulation.
