First results in coherent harmonic generation using the undulator at the MAX-lab electron storage ring

In English An experiment in coherent harmonic generation has been performed at the MAX-lab electron storage ring in Lund. Coherent photons were produced in the third harmonic of a Nd:YAG laser focused on the electron beam in a permanent magnet undulator. The number of coherent photons, the linewidth, the current dependence and other parameters have been measured.
