Tunable-ultraviolet generation by sum-frequency mixing
Continuous wave radiation tunable across a wide wavelength range may be generated simply and conveniently by mixing the output of a commercial c-w dye laser with various output lines from an argon- or krypton-ion laser in a nonlinear cyrstal located outside both laser cavities. Because ion lasers provide lines a wavelengths between the ultraviolet and the infrared, a wide range of sum-frequency wavelengths can be obtained without changing the dye or optics in the c-w laser and without use of the less-efficient coumarin dyes. Sum-frequency mixing can provide both pulsed and c-w coherent radiation across an extended range in the ultraviolet. Because of this, frequency-mixing techniques are worth consideration in any application requiring a source of tunable uv radiation.
