ABSTRACT:
A light source composed of a semiconductor laser and a nonlinear optical element which converts a laser beam emitted from the semiconductor laser to a laser beam having a shorter wavelength, disposed in the path of a laser beam produced by the laser, the nonlinear optical element containing a compound represented by formula (I): ##STR1## wherein Z.sup.1, Z.sup.2, X and n are as defined in the specification, of formula (II) ##STR2## wherein Z.sup.3 and Z.sup.4 are defined in the specification, or an acid adduct therefore. the nonlinear optical element exhibits high transmittances to blue light and generates a laser beam having a shorter wavelength than that of the laser applied.
