摘要： When one tries to obtain high-output wavelength conversion light of class W, the internal temperature of a wavelength conversion element rises significantly to cause an undue variation in phase matching wavelength and thereby it is difficult to match the wavelength of a fundamental wave to the phase matching wavelength. A part of the output of the fundamental wave or pumping light propagating on a fiber is thereby absorbed by doping the fiber with a rare earth element at a set concentration, and the temperature of a fiber grating is raised by heating the fiber grating with heat produced through the absorption. Consequently, the wavelength of the fundamental wave obtained through the fiber grating by widening the grating interval is substantially matched to the phase matching wavelength which can be converted by the wavelength conversion element, and a wavelength converter ensuring a stable high output up to class W is provided.

摘要： There has been a problem that interference noise called speckle noise occurs in a two-dimensional image display device using laser, and there is no applicable green light source although the speckle noise can be reduced by using a multi-wavelength light source. The present invention adopts a Yb-doped clad pump fiber (103) which is a rare-earth-doped fiber as a laser activation substance, whereby a peak of a fluorescence spectrum can be significantly increased as compared with a case of using an oxide crystal, and a variation width of an oscillation wavelength can be increased. Further, since the rare-earth-doped fiber is used as a fiber amplifier without providing laser mirrors at both ends thereof, control for a resonator length, which has been required in a conventional device (wherein an oxide crystal is used as a laser medium), is dispensed with, and thereby high-speed wavelength control is achieved, resulting in reduction in speckle noise when it is mounted on a two-dimensional image display device.

摘要： After forming domain inverted layers 3 in an LiTaO3 substrate 1, an optical waveguide is formed. By performing low-temperature annealing for the optical wavelength conversion element thus formed, a stable proton exchange layer 8 is formed, where an increase in refractive index generated during high-temperature annealing is lowered, thereby providing a stable optical wavelength conversion element. Thus, the phase-matched wavelength becomes constant, and variation in harmonic wave output is eliminated. Consequently, with respect to an optical wavelength conversion element utilizing a nonlinear optical effect, a highly reliable element is provided.
