Light wavelength converter
专利汇可以提供Light wavelength converter专利检索，专利查询，专利分析的服务。并且PURPOSE:To obtain a small-sized light wavelength converting element with high light conversion efficiency by making semiconductor laser light incident to one terminal of a light guide made of nonlinear optical crystal, and passing it through the light guide again by a total reflecting mirror provided at the other terminal. CONSTITUTION:For example, Ti is diffused thermally into a Z surface of LiNbO33 to form a light guide 4'. An Al film is vapor-deposited on one terminal of the light guide 4' to form the total reflecting mirror 6. A dielectric multi- layered film 8 which transmits a basic wave and reflects converted light (2nd higher harmonic) at right angles is arranged on the other end surface 9 between convergent rod lenses 7a and 7b to obtain the light wavelength converting element constituted in combination with a semiconductor laser 1'. Thus, the basic wave of the laser 1' is reflected by the membrane of said mirror 6 to propagate in a length twice as long as the light guide 4'. The 2nd higher harmonic is obtained with efficiency about four times as high as usual by a method which utilizes anisotropic variation in refractive index with temperature on phase matching condition.，下面是Light wavelength converter专利的具体信息内容。
