Narrow Bandwidth Double Wavelength Pulsed Dye Laser for Use in Plasma Diagnostics

Nitrogen laser pumped pulsed dye laser system was constructed for use in discharge plasma diagnostics. Double dye laser oscillators with grazing incidence configuration were simultaneously pumped by the single nitrogen laser, thus narrow bandwidth double wavelength laser beams were obtained with a sufficient output power. The dye laser system is applicable to the laser induced fluorescence spectroscopy and the laser optogalvanic spectroscopy
