Mode locking - Wikipedia
WEBMode locking is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, on the order of picoseconds (10 −12 s) or femtoseconds (10 −15 s). A laser operated in this way is sometimes referred to as a femtosecond laser, for example, in modern refractive surgery.
Mode Locking – active, passive, modelocking, ultrashort pulses, …
WEBMode locking is achieved by using some kind of mode locking device (mode locker) within the laser resonator – either an active element (an optical modulator) or a nonlinear passive element (a saturable absorber).
Phase and Frequency Locking of Diode Lasers - TOPTICA Photonics AG
WEBThere are many ways to lock a laser´s phase or frequency. They do, however, all follow the same basic principles based on a feedback loop, which is diagrammatically sketched in Figure 1. Each application note contained in this collection focuses on …
Active Mode Locking – actively mode-locked laser, modulator, …
WEBThis article specifically addresses active mode locking, which involves the periodic modulation of the resonator losses or of the round-trip phase change. This can be achieved e.g. with an acousto-optic or electro-optic modulator, a Mach–Zehnder integrated-optic modulator, or a semiconductor electroabsorption modulator.

Mode-locked Lasers – ultrashort pulses, modelocked, picosecond ...
WEBA mode-locked laser is a laser to which the technique of active or passive mode locking is applied, so that a periodic train of ultrashort pulses is emitted. See the articles on mode locking and mode locking devices for more details on mode-locking techniques; the present article focuses on the lasers themselves.
Laser : Fundamentals - Mode-locking - optique-ingenieur.org
WEBThe term “mode-locking” comes from the analysis of the various frequencies. A laser operating under these conditions will emit over several different frequencies due to the rapid modulation of the modulator. They are also imposed by the optical cavity, spaced out by : the longitudinal modes of the cavity.
WEBActive Mode Locking. For simplicity, we assume, that the laser operates in the transverse fundamen-tal modes and, therefore, we only have to treat the longitudinal modes of the laser similar to a simple plane parallel Fabry-Perot resonator (Figure: 5.1).
Mode Locking - Benjamin Klein
WEBIn a modelocked laser, we will take steps to ‘lock’ the phases of all the lasing modes so that they have a definite relationship to one another. The reason that this is desirable will be described below.
