Photon beams both from classical Bremsstrahlung and, notably, from backscattering laser light off e{sup {+-}} beams are considered. The differential cross sections d{sigma}/dcos {theta} of the three reactions are calculated analytically and used as observables in a {chi}{sup 2} analysis under identical assumptions on machine parameters. The constraints emerging from the use of laser photon beams appear very encouraging, are independent of {kappa}{sub Z} and {lambda}{sub Z} and impressively underline the importance of realizing laser photon beams at the NLC.
