Continuously Tunable Pulsed Ultraviolet Light Source

A technique is described for producing a continuously tunable uv source using the broadband emission from a dye laser as input to a rotatable KDP crystal. A theoretical model is developed based on mixing of emission band components which are spaced equidistant and symmetrically about the part of line that corresponds to maximum SHG (Δk = 0). This model agrees well with the observed spectral line narrowing, relatively high experimental conversion efficiency, and experimental tuning curve.
