Intracavity frequency-converted optically-pumped semiconductor laser with red-light output

摘要

In a branched resonator OPS-laser arrangement, a combination of intra-cavity optical parametric generation and intra-cavity sum-frequency mixing provides output radiation in a range between about 550 nanometers about 700 nanometers from an OPS fundamental wavelength in a range between about 900 nm and about 1100 nm.
