WebSome types of lasers can hardly work in continuous-wave operation, but only in pulsed operation; that can have different reasons: It some cases, one can obtain a sufficiently high laser gain only with pump intensities which are practical only for pulsed pumping.
WebA mode-locked laser is capable of emitting extremely short pulses on the order of tens of picoseconds down to less than 10 femtoseconds. These pulses will repeat at the round trip time, that is, the time that it takes light to complete one round trip between the mirrors comprising the resonator. today\u0027s rising stocksWebThe use of a saturable absorber as a passive mode locker in a solid-state laser can introduce a tendency for Q -switched mode-locked operation.
