The physics potential of

− linear colliders is summarized in this report. These machines are planned to operate in the first phase at a center-of-mass energy of 500
GeV, before being scaled up ...to about 1
TeV. In the second phase of the operation, a final energy of about 2
TeV is expected. The machines will allow us to perform precision tests of the heavy particles in the Standard Model, the top quark and the electroweak bosons. They are ideal facilities for exploring the properties of Higgs particles, in particular in the intermediate mass range. New vector bosons and novel matter particles in extended gauge theories can be searched for and studied thoroughly. The machines provide unique opportunities for the discovery of particles in supersymmetric extensions of the Standard Model, the spectrum of Higgs particles, the supersymmetric partners of the electroweak gauge and Higgs bosons, and of the matter particles. High precision analyses of their properties and interactions will allow for extrapolations to energy scales close to the Planck scale where gravity becomes significant. In alternative scenarios, i.e. compositeness models, novel matter particles and interactions can be discovered and investigated in the energy range above the existing colliders up to the TeV scale. Whatever scenario is realized in Nature, the discovery potential of

− linear colliders and the high precision with which the properties of particles and their interactions can be analyzed, define an exciting physics program complementary to hadron machines.
We have calculated inclusive one- and two-jet production in photon-photon collisions superimposing direct, single resolved and double resolved cross sections. The direct and single resolved cross ...sections are calculated up to next-to-leading order. The double resolved two-jet cross section is estimated from leading order with a
k factor taken from the single-jet prediction in next-to-leading order. The results are compared with recent experimental data from the TOPAZ and AMY Collaborations at TRISTAN. Good agreement is found between experiment and the theoretical results.
We have calculated inclusive one- and two jet production in photon-photon collisions superimposing direct, single-resolved and double-resolved cross sections for center of mass energies of the LEP1, ...LEP2 and NLC range. The direct and single-resolved cross sections are calculated up to next-to-leading order. The double-resolved two-jet cross section is calculated only in LO with a k factor estimated from the NLO one jet cross section. Various differential cross sections as functions of transverse momenta and rapidities of the jets are evaluated.
