/ˈmoʊdˌlɑkt/

Origin: Formed within English, by compounding. Etymons: mode n., locked adj.²

Etymology: < mode n. + locked adj.² Compare mode-locking n., and slightly later mode-lock v.

Physics.

Of a laser: that employs mode-locking. Of a pulse: produced by such a laser.

mode-locked1965

1965 IEEE Jrnl. Quantum Electronics 1 16/2 The light pulses from a mode-locked laser were observed with a magnetically focussed photo-multiplier tube.

1971 Sci. Amer. June 24/1 As the energy in the laser cavity is built up and then decays, a string of such mode-locked pulses emerges from the partially transmitting mirror in the front of the cavity.

1993 Analyt. Chem. 65 849 The technique makes use of a frequency-doubled mode-locked Nd:YAG laser to repetitively excite the molecules.
