Abstract
A nonlinear optical device is provided which uses nonlinear optical materials that transmit a fundamental wave and generated higher harmonics, and have optical absorption maximums based on an electronic transition between wavelengths of the fundamental wave and the generated higher harmonics. Therefore, by emitting higher harmonics having a wavelength within an optical transmission region between wavelengths of the two optical absorption maximums, materials can be used which have a long wavelength at their absorption edge and a large .beta. value which have been considered unsuitable in the prior art. As a result, a device with high conversion efficiency can be realized.
