Potassium-lithium niobate crystals. |
摘要 |
The invention provides a method of manufacturing stoichiometric potassium-lithium niobate crystals. Such crystals exhibit a high degree of double refraction and can suitably be used to double the frequency of a light wave with noncritical phase matching. By virtue of the temperature dependence of the nonlinear optical properties and the possibility of doubling the frequency at room temperature and at wavelengths from 800 to 850 nm the material according to the invention is very suitable for use in cooperation with semiconductor lasers. |
