摘要：A laser device includes a resonant cavity with a gain medium therein, and firstand second reflectors at either end, to form a quasi- isotropic laser. A feedback section isformed between the second reflector and a third reflector. A polarizer and modifier areprovided in the feedback section. The polarizer and modifier can modify a variety ofparameters, for example the polarization, phase, intensity or frequency of the feedback.The light feedback into the resonant cavity has an intensity much less than that within theresonant cavity, but sufficient to overcome any residual anisotropies. Control of themodifier causes the device to be operated in one of two or more polarization modes.
