Generation of blue coherent light from a continuous-wave semiconductor laser using an organic crystal-cored fiber

摘要: Efficient frequency doubling of a continuous‐wave semiconductor laser was attained by using nonlinear optical fiber with single crystal core an organic 3,5‐dimethyl‐1‐ (4‐nitrophenyl)pyrazole. The second‐harmonic power generated 15 mm length the reached 0.16 mW from incident 16.6‐mW fundamental at 884 nm. Nonlinear properties and fabrication technique are also reported.
