Dual-wavelength operation and regenerative amplification of self-seeded laser

We demonstrate simultaneous dual-wavelength operation in the coupled-cavity dye laser with self-seeding technique. The laser cavity can be decomposed with two grazing-incidence cavities and a standing wave cavity. The output beams are independently tunable and collinear. Operational characteristic have been investigated by changing the cavity length, incident angle, and the like. We also discuss the regenerative amplification of self-seeded dye laser.
