1. A distributed resonator laser system, comprising:
a first distributed resonator comprising:
a rear retroreflector having high reflectivity,
a laser gain medium, and
an output retroreflector having a reflectivity substantially less than that of the rear retroreflector,
wherein said output retroreflector is also a first mirror of a second distributed resonator, said second distributed resonator having a retroreflector disposed remotely from said first mirror, such that for light within said first distributed resonator impinging on said output retroreflector at an angle that excites a resonance in said second distributed resonator, said second distributed resonator has, at a series of periodic wavelengths, an effective reflectivity substantially higher than that of said output retroreflector, such that said first distributed resonator lases at said periodic wavelengths even when the position of said retroreflector of said second distributed resonator changes.
