High-statistical data on the gamma gamma -> K (+) K (-) and gamma gamma -> K (0) KI double dagger (0) reactions constitute the last missing link in investigations of light scalar mesons f (0)(980) and a (0)(980) in photon-photon collisions. It is expected that the manifestation of the four-quark structure of the f (0)(980) and a (0)(980) resonances in these reactions will be very peculiar. The possibilities of the observation of scalar contributions in the gamma gamma -> K (+) K (-) and gamma gamma -> K (0) KI double dagger (0) reactions near their thresholds at modern colliders have been estimated.
