Abstract: PROBLEM TO BE SOLVED: To overcome the problem that conventionally, when light is introduced into an optical fiber having a function of amplifying the light of an excitation laser, the light leaking from the optical fiber due to mismatch in the NA between the excitation laser and the optical fiber or due to shift after adjustment is absorbed by a coated material such as a buffer or a jacket of the optical fiber, and this may cause hazard such as heat generation and deterioration in the characteristics. SOLUTION: A translucent material is disposed adjacent to the rear end of the coated material in the propagation direction of the light in the coated optical fiber, the coated material surrounding the peripheral face of a coated optical fiber comprising a light-propagating medium, so that at least part of the light propagating in the coated optical fiber is transmitted and emitted to the outside through a sloped part of the translucent material. This avoids intensive absorption of the light energy by the coating, and heat generation and deterioration in the characteristics accompanying the absorption. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To improve stability and reliability without complicating the configuration and adjustment in a laser beam generator. SOLUTION: The laser beam generator 1 having a stimulation light source for generating the stimulation light of continuous waves and a resonator utilizing thermal lens effect by heat generation at a stimulating position comprises a laser medium 3, an intermediate medium 4, and a reflection means 5 as the components. By adjusting the stimulating position in a direction orthogonally crossing the optical axis of the stimulation light, the interface between the components (the laser medium and a saturable absorber) and the intermediate medium (an air layer) is formed as a curved surface to correct an angle error concerned with the parallelism of the components in the resonator.

Abstract: PROBLEM TO BE SOLVED: To make it possible to reduce an installation area and to enhance the effect of heat radiation so as to enhance reliability by forming a place inclusive of the optical path of a wavelength conversion resonator near to a perpendicular surface. SOLUTION: A base substrate 5 consists of a base and flanks. This base constitutes an installation surface 52. The wavelength conversion resonator 4 and a laser beam source 1 which generates a basic wave 2 are installed on an arrangement reference plane 51 which is the flank nearly perpendicular to the installation surface 52. The wavelength conversion resonator 4 is installed longitudinally on the arrangement reference plane 51 and, thereafter, the plane inclusive of the optical path of the wavelength conversion resonator 4 has a structure nearly perpendicular surface. The optical path by the basic wave 2 and an output laser beam 3, etc., which is the converted harmonic wave is constituted within the perpendicular plane. the installation area is preferably taken to some extent for the purpose of the mechanical stabilization of the installation; for example, the area of the installation surface 52 is preferably so set as to be larger than the upper projection area of the device unit. The surface of the arrangement reference plane 51 on the side where the laser beam source 1 and the wavelength conversion resonator 4 are not mounted performs the function of heat radiation.

Abstract: PROBLEM TO BE SOLVED: To provide a stable wavelength converting light source and obtain short-wavelength laser light of high output. SOLUTION: A wavelength conversion system consists of a basic wave light source 11 which generates basic wave light, an external resonator 30a composed of plural mirrors 201, 202, 203, and 204 having high reflection factors to the basic wavelength of the light source, and a nonlinear optical element 17 which is provided in the external resonator 30a and generates the 2nd higher harmonic of the basic wave. The nonlinear optical element 17 is formed by optically joining the same kind or different kinds of material and spatially separates the basic wave light and 2nd higher harmonic light. A means for spatial separation is obtained by using the birefringence of optical crystal. Further, a means for the said joining employs diffusion joining by which joined parts are optically polished into planes, joined together, and then pressed and heated. As the nonlinear optical element 17, beta-BaB2 O4 , CsLiB6 O10 , KTi0P04 , LiNbO3 , LiB3 O5 , or KNbO3 is used.
