We study the production of a J/psi meson in association with one or two jets in gamma gamma collisions concentrating on the direct-photon contribution. which is expected to be dominant for large J/psi -meson transverse momentum and/or large dijet invariant mass. We work at leading order in the factorization formalism of nonrelativistic QCD and include all relevant colour-octet processes. We present distributions in J/psi -meson transverse momentum and rapidity appropriate for CERN LEP2, a future e(+)e(-) linear collider, and a possible gamma gamma collider mode of the latter. In the case of the e(+)e(-) linear collider, we assume the beamstrahlung spectrum appropriate for DESY TESLA. (C) 2001 Elsevier Science B.V. All rights reserved.
