We study the cross sections for the production of intermediate mass Higgs bosons via the reactions [ital e][sup [minus]][gamma][r arrow][nu][sub [ital e]][ital W][sup [minus]][Phi][sup 0], [ital e][sup [minus]][gamma][r arrow][nu][sub [ital e]][ital H][sup [minus]][Phi][sup 0], [ital e][sup [minus]][gamma][r arrow][ital e][sup [minus]][ital Z][sup 0][Phi][sup 0], and [ital e][sup [minus]][gamma][r arrow][ital e][sup [minus]][ital H][sup +][ital H][sup [minus]] in the minimal supersymmetric standard model (with [Phi][sup 0]=[ital H][sup 0],[ital h][sup 0] and, where possible, [ital A][sup 0]) at TeV energies, taking into account [ital b]-tagging capabilities. We find that the rates for [ital e][sup [minus]][gamma][r arrow][nu][sub [ital e]][ital W][sup [minus]][Phi][sup 0] are large enough to permit the detection of at least one between [ital h][sup 0] and [ital H][sup 0] over the whole intermediate mass range of [ital M][sub [ital A]][sup 0], at all tan[beta], using the ([ital jj])([ital b[bar b]]) final state. The [ital CP]-odd neutral [ital A][sup 0] and the charged [ital H][sup [plus minus]]'s can be detected via the processes [ital e][sup [minus]][gamma][r arrow][nu][sub [ital e]][ital H][sup [minus]][ital A][sup 0], with [ital A][sup 0][r arrow][ital b[bar b]], and [ital e][sup [minus]][gamma][r arrow][ital e][sup [minus]][ital H][sup +][ital H][sup [minus]], resorting to the leptonic decay [ital H][sup [plus minus]][r arrow][nu][sub [tau]][tau][sup +]([bar [nu]][sub [tau]][tau][sup [minus]]), but only for [ital M][sub [ital A]][sup 0][approx]60 GeV. Finally, we present explicit formulas for the helicity amplitudes of these processes.
