  We study a three-level quantum refrigerator which is driven by a generic
light state, even a nonclassical one. With the help of P function expansion of
the driving light, we obtain the heat current generated by different types of
light states. It turns out all different input light states give the same
coefficient of performance for this refrigerator, while the cooling power
depend not only on the light intensity but also the specific photon statistics
of the driving light. Comparing with the coherent light with the same
intensity, the driving light with super(sub)-Poissonian photon statistics could
raise a smaller (stronger) cooling power. We find that this is because the
bunching photons would first excite the system but then successively induce the
stimulated emission, which draws the refrigerator back to the starting state of
the cooling process and thus decreases the cooling current generation. This
mechanism provides a more delicate control method via the high order coherence
of the input light.
