%X We describe a kHz single photon wavelength modulation technology to realize the locking reference signal of the laser frequency. By detecting the single photon acetylene gas absorption spectrum and by amplifying the lock-in the discrete single photon response pulse,we achieve the laser frequency stabilized in real time.The 1.5μm distribution feedback semiconductor laser output frequency is stabilized at acetylene gas absorption peaks,and the typical laser frequency fluctuation is less than 25 MHz within 175 s.This single photon wavelength modulated absorption spectrum technology eliminates the high background noise in low frequency range and can be used in the quantum communication system and optical wavelength division multiplex.
