As part of the positron source R&D for future e super(+) -- e super(-) colliders and Compton based compact light sources, a high finesse non-planar four-mirror Fabry-Perot cavity has recently been installed at the ATF (KEK, Tsukuba, Japan) 1. The first measurements of the gamma ray flux produced with a such cavity using a pulsed laser is presented here. We demonstrate the production of a flux of 2.7 plus or minus 0.2 gamma rays per bunch crossing ( similar to 3 x 10 super(6) gammas per second) during the commissioning.
