Query: A method for independent and continuous tuning of $N$ lasers
  phase-locked to the same frequency comb   We present a method of phase-locking any number of continuous-wave lasers to
an optical frequency comb (OFC) that enables independent frequency positioning
and control of each laser while still maintaining lock to the OFC. The scheme
employs an acousto-optic modulator (AOM) in a double pass configuration added
to each laser before its light is compared by optical heterodyne with the comb.
The only requirement is that the tuning bandwidth of the double pass AOM setup
be larger than half the OFC repetition rate. We demonstrate this scheme and
achieve an arbitrary frequency tuning precision, a tuning rate of 200~MHz/s and
a readout precision at the 1~kHz level.
