A New Laser Technique for Simultaneous Two Wavelength Studies

  • Herschel S. Pilloff
Conference paper


A new technique has been developed which allows simultaneous two wavelength selection in both inhomogeneously and homogeneously broadened lasers. The two laser beams are collinear and collimated, have mutually orthogonal polarizations, and, in general, can be temporally synchronized. This technique has been applied to the pulsed nitrogen laser-pumped dye laser and features continuous tunability of the two wavelengths throughout the entire optical gain region of the particular dye solutions used. Following the description of this device, the extension of this technique to other lasers and a few potential applications will be briefly discussed.
