ABSTRACT:
A fiber type optical wavelength converter comprising a core, and a clad. The core is made of nonlinear optical crystal that converts the primary light or straight polarization of a frequency of .omega., which enters and propagates in the direction of the center axis of the core, into a second harmonics having a vibrating surface normal to a vibrating surface of the primary light and having a frequency of 2.omega.. The nonlinear optical crystal also satisfies n.sup..omega. .gtoreq.n.sup.2.omega. where n.sup..omega. is a refractive index to the primary light and n.sup.2.omega. is a refractive index to the second harmonics.
