The competition between two time-delayed feedback may cause frustration in selecting an oscillation mode, when there exist many potential modes with subtly different stabilities. Thus, a slight change in cavity length enables an oscillation in a quite different mode. This phenomenon is examined employing a diode-pumped microchip Nd:YVO4 laser with multimode fiber feedback which forms a compound cavity. In particular, single mode laser operation in which mode-partition noise is not essential but the intrinsic noise fluctuation in intensity is dominant for the frustration is obtained.
