Abstract
In a semiconductor laser wavelength conversion device comprising a semiconductor laser beam souce, a lens, a single crystal of a non-linear optical material and a filter, the non-linear optical material is represented by the general formula, A--(Cx)--B, where (Cx) is --(CH)--or --CH.dbd.CH--C(.dbd.CH)--, A and B are each atomic group comprising a .pi.-electron conjugated structure containing at least one electron withdrawing group or one electron donating group. The device can generate a second harmonic wave having an intensity of 4 or more stronger than that of urea and having a cutoff wavelength of 420 nm or less.
