Is it possible to use the photon flux of a laser as clock source using a

As far as I know:  Photon-counters only work at low rate of photons
and lasers only work at high rate of photons.



Well, in deep space optical comm, we send many photons with a laser, and we use pulse position modulation at the receiver detecting single photons (or "few photons"), by which we can send "many bits/photon" (e.g. if you have 256 possible time slots in which the photon can arrive, you have 8 bits/photon)
