  We calculate the partial widths of the light Higgs boson in the Littlest
Higgs model. The loop-induced Higgs coupling to photon pairs, which is
especially sensitive to effects of the new TeV-scale particles running in the
loop, can be probed with high precision at a photon collider in the process
gamma gamma --> H --> b bbar. Using the parameters of the Littlest Higgs model
measured at the LHC one can calculate a prediction for this process, which will
serve as a test of the model and as a probe for a strongly-coupled UV
completion at the 10 TeV scale.
