A method and apparatus for executing branch instructions is provided. A stator winding includes a plurality of phases, each including at least a first filar and a second filar extending circumferentially around the stator core to form a plurality of layers. The apparatus can also include an indicator that is disposable between a first, operational position and a second, rest position. The wavelength-selective reflective elements are arranged so that the laser system operates stably in the coherence collapse lasing regime.
