DUAL-WAVELENGTH OPERATION OF A SELF-SEEDED DYE-LASER OSCILLATOR

We demonstrate simultaneous dual-wavelength operation of a self-seeded dye laser. The laser cavity consists of one dye cell, two pairs of gr ating and tuning mirrors, and two reflecting mirrors. This configurati on can be decomposed with two grazing-incidence cavities and a standin g-wave cavity. The self-seeded dual-wavelength output beams are collin ear and independently tunable. We were able to vary the output powers at the two wavelengths smoothly by changing the cavity length of a mas ter oscillator. (C) 1996 Optical Society of America
