Optical parametric oscillators

Article Abstract:

The development of continuously tunable coherent light sources for lasers would have broad applications in research and industry, but the discrete-wavelengths of conventional lasers has made the development of tunable oscillators difficult. Advances in nonlinear optical materials research are now making optical parametric oscillators practical. Optical parametric oscillators are solid state sources of broadly tunable coherent radiation ranging from near UV to the mid-IR spectrum. They can operate down to the femtosecond time domain. Current developments in B-barium borate (BBO), lithium triborate (LBO) and potassium titanyl phosphate (KTP) optical parametric oscillators are discussed in detail.
