Simultaneous two-wavelength selection in the N2 laser-pumped dye laser

Abstract

A technique is reported which allows simultaneous two‐wavelength selection in the N2 laser‐pumped dye laser. The two wavelengths are continuously tunable anywhere within the optical gain region of the particular dye solution used, and the two output beams are collinear and collimated, have mutually orthogonal polarizations, and in general can be temporally synchronized. Following the description of this device, the extension of this technique to other lasers and a few potential applications will be briefly discussed.
