Abstract

There has recently been much interest in compact sources of blue and green radiation for a wide variety of uses, including optical data storage, color displays, and undersea optical communications. The advent of powerful semiconductor diode lasers has stimulated the development of miniature blue laser devices based on nonlinear frequency upconversion of the laser diode radiation. Efficient generation of blue/green light requires finding compatible combinations of lasers (e.g., semiconductor diode lasers or diode pumped solid state lasers) and nonlinear materials which can be combined in practical device configurations to produce visible light by processes such as second harmonic generation and sum frequency mixing.
