Simple setup for rapid testing of third-order nonlinear optical materials.
A relatively inexpensive and versatile degenerate four-wave mixing setup is described utilizing a nitrogen laser pumped dye laser. Samples can be screened rapidly, which is demonstrated with the example of a semiconductor doped glass having a nonlinear susceptibility x((3)) ~ 10(-11)-10(-10) esu.
