Abstract: (Springer)

An analysis of the production ofKS0KS0 andK±Ks0π∓ by two quasi-real photons is presented. The cross section forγγ→K0

, which is given for the γγ invariant mass range fromK

\bar K

threshold to 2.5 GeV, is dominated by thef′(1525) resonance and an enhancement near theK

\bar K

threshold. Upper limits on the product of the two-photon width times the branching ratio intoK

\bar K

pairs are given forΘ(1700),h(2030), and ξ(2220). For exclusive two-photon production ofK±Ks0π∓ no significant signal was observed. Upper limits are given on the cross section ofγγ→K+

\overline {K^0 }

π− orK−K0π+ between 1.4 and 3.2 GeV and on the product of the γγ width times the branching ratio into theK
