We discuss in this paper, highly efficient techniques for CW non-linear frequency conversion using novel pump laser sources and high efficiency laser gain materials. We also address the limitations of non-linear conversion processes and evaluate the performance of conventional non-linear optical materials that have recently been modified for non critical phase matching (NCPM) applications, such as NCPM-KTP. Moreover, we outline the significant improvements in performance of new non-linear materials for frequency conversion of fundamental wavelength laser sources, utilizing recent advances in application tailored materials with high non-linear coefficients such as PPLN. In particular, the issues related to efficient intracavity higher harmonic generation, including intracavity doubling and intracavity tripling as well as intracavity and extracavity optical parametric oscillator development are described.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
