Measuring the Gamma(h -> gamma gamma)Br(h -> bb) decay at the photon collider at TESLA is studied for a Standard Model Higgs boson of mass m_h = 120 GeV. The main background due to the process gamma gamma -> QQ(g), where Q = b,c, is estimated using the NLO QCD program (G. Jikia); the results obtained are compared with the LO estimate. Using a realistic luminosity spectrum and performing a detector simulation, we find that Gamma(h -> gamma gamma)Br(h -> bb) can be measured with an accuracy better than 2% after one year of photon collider running.
