Diode end pumped laser and harmonic generator using same

摘要: A second harmonic, optical generator is disclosed in which a laser diode produces an output pumping beam focused by means of graded, refractive index rod lens into lasant material, such as Nd:YAG, disposed within resonator to pump the material and excite at fundamental wavelength. non-linear electro-optic MgO:LiNbO3 coupled excited, mode produce interaction with wavelength producing harmonic. In one embodiment, gain medium are defined pair reflectors, formed on face medium. another non-linear, doped ion that doubling co-extensive volume. external gai for improved stability harmonic generation process. andthe bonded together optically transparent cement form mechanically stable, monolithic structure. has reflective faces thereon define ring decouple reflections from back stability.
