ABSTRACT:
A pair of single mode laser light sources are tuned to opposite sides of a frequency response curve which forms either a peak or a valley. The laser light sources are offset in frequency from each other by a fixed frequency interval. The average frequency may thus be stabilized at the peak or valley. A third single mode laser light source, offset in frequency at a fixed point between the frequencies of the pair of laser sources, may thus be actively stabilized at the peak or valley. The frequency spectrum is simple, and of high power.
