We evaluate the prospects for measuring B(h{r_arrow}{gamma}{gamma}) for a standard-model-like Higgs boson at the Next Linear e{sup +}e{sup -} Collider in the e{sup +}e{sup -}{r_arrow}Z{sup {star}}{r_arrow}Zh and e{sup +}e{sup -}{r_arrow}{nu}{sub e}{ovr {nu} }{sub e}h production modes.Relative merits of different machine energy/luminosity strategies and different electromagnetic calorimeter designs are evaluated. We emphasize the importance of measuring B(h{r_arrow}{gamma}{gamma}) in order to obtain the total width of a light Higgs boson and thereby the b{ovr b} partial width that will be critical in discriminating between the standard model Higgs boson and the Higgs boson of an extended model. {copyright} {ital 1997} {ital The American Physical Society}
