Abstract
A resonator (1) for electromagnetic waves with a stabilizer can, for example, be part of a mode-coupled fiber laser. The stabilizer (2) is provided to stabilize the effective length of the resonator (1). Stabilization is accomplished in a first embodiment via two temperature controllers (3, 4) controlling the temperature of a first portion (L1) and the temperature of a second portion (L2) of the resonator (1). The temperature of the second portion (L2) is controlled as a function of an error signal generated by deviations of the resonator (1) from a nominal length. The second portion (L2) is significantly shorter than the first portion (L1).
