The intermediate mass Higgs boson can be abundantly produced through the process [ital e][sup [minus]][gamma][r arrow][ital W][sup [minus]][ital H][nu] at TeV [ital e][sup [minus]][gamma] colliders, which are realized by the laser backscattering method. We search for the signature of [ital W][sup [minus]][ital H][r arrow]([ital jj])([ital b[bar b]]) plus missing transverse momentum, with and without considering [ital b] tagging. We also analyze all the potential backgrounds from [ital e][sup [minus]][gamma][r arrow][ital W][sup [minus]][ital Z][nu], [ital W][sup [minus]][ital W+][ital e[minus]], [ital ZZe][sup [minus]], [ital [bar t]b][nu], and [ital t[bar t]e][sup [minus]]. With our selective acceptance cuts these backgrounds are reduced to a manageable level. We find that for the entire intermediate mass range 60--150 GeV the Higgs boson discovery should be viable. We also present detailed formulas for the helicity amplitudes of these processes.
