A 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.
It can mean single-transverse-mode operation, where a laser operates on a single kind of transverse resonator mode, which is almost always a Gaussian mode (although operation on a single higher-order mode is also possible, e.g. by using some diffractive element in the laser resonator).
