Nitrogen pumped dye lasers cover the spectral range from 360 nm to 950 nm. We offer both fixed frequency and tunable models. In this dye laser system, the dye solution is optically pumped with a nitrogen laser and produces pulsed visible laser light. Exchanging dye cuvettes alters the dye laser output wavelength. Our system enables the researcher to easily and inexpensively produce laser light over a broad spectral range. Spectra-Physics offers the DUO series dye lasers for the research oriented VSL-337ND-S nitrogen laser and the DYE series for the ultra compact VSL-337 nitrogen laser. Based on our history with dye lasers, the new DUO and DYE series lasers offer greater flexibility, improved performance, and increased ease of use.
