phase lockn.

Brit.

/ˈfeɪz lɒk/, U.S.

/ˈfeɪz ˌlɑk/

Origin: Formed within English, by compounding. Etymons: phase n.², lock n.²

Etymology: < phase n.² + lock n.²

Originally and chiefly Electronics.

The stabilization of the frequency of an oscillator, laser, etc., relative to that of another, esp. by means of phase-locking; the state of being stabilized in this way. Frequently attributive.

1973 Gramophone Jan. 1433/3 He showed that an IC ‘chip’, using phase-lock techniques, can provide all the decoding functions.

1989 I. Stewart Does God play Dice? xiii. 278 Three periods of the forcing oscillation may be the same as four periods of the natural one, a 3:4 phase-lock.

2000 Adv. Space Res. 25 1145 The term Δω represents the frequency difference between the lasers, which can be large..and will not even be constant. This makes the phaselock between the two lasers absolutely necessary!
