摘要： A laser light source device, which is capable of multi-wavelength oscillation, includes a laser light source; and a laser cavity including (i) a fiber, (ii) a first fiber grating provided at a side of the fiber toward the laser light source and having a plurality of reflection peaks, and (iii) a second fiber grating provided at a light emission end of the fiber and having a plurality of reflection peaks. Further, the laser light source includes a wavelength converter converting a fundamental wave emitted from the laser cavity into a harmonic wave; a reflection wavelength varying unit shifting reflection wavelengths of the reflection peaks of the second fiber grating; and a controller controlling phase matching conditions of the wavelength converter.

摘要： Since the absorption of a fundamental wave by a fiber increases if it is tried to obtain a wavelength conversion light of watt-class high output, the fiber length needs to be shortened. However, since oscillation efficiency conversely decreases if the fiber length is shortened, it is difficult to obtain a high-output fundamental wave. Thus, by reflecting an excitation light incident on the fiber in the fiber, the excitation light is efficiently absorbed to amplify the fundamental wave with a high gain. Further, by shortening the fiber length, the absorption of the fundamental wave is also reduced to improve a fundamental wave output. Consequently, a wavelength converter capable of ensuring a stable high output up to watt-class is achieved.
摘要翻译：由于如果试图获得瓦特级高输出的波长转换光，则由于光纤吸收基波而增加，所以需要缩短光纤长度。然而，由于如果光纤长度缩短，振荡效率相反地降低，所以难以获得高输出基波。因此，通过反射入射到光纤中的光纤上的激发光，有效地吸收激发光，以高增益放大基波。此外，通过缩短光纤长度，也减小了基波的吸收，以改善基波输出。因此，实现能够确保稳定的高输出到瓦特级的波长转换器。

摘要： A two-dimensional image display device using a Yb-doped clad pump fiber 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： A wavelength conversion element is provided with a substrate including a nonlinear optical single crystal having a periodically poled structure, the visible light transmittance of the substrate is 85% or higher when ultraviolet light is irradiated to the substrate, and laser light having an average output of 1 W or more is outputted by shortening the wavelength of laser light having a wavelength of 640 nm to 2000 nm. By improving visible light transmission characteristics when the ultraviolet light is irradiated in this way, the breakdown of crystal can be prevented and the stabilization of output characteristics at high output can be realized. As a result, the absorption of green light induced by ultraviolet light can also be suppressed, and the saturation of output and the breakdown of crystal can be avoided.

摘要： Upon obtaining green light as wavelength converted light by causing infrared light to be incident on a wavelength conversion element, the absorption of the green light occurs due to the generation of ultraviolet light as sum-frequency light of the infrared light and the green light in the wavelength conversion element and the destruction of a crystal composing the wavelength conversion element occurs due to heat generated at this time. In a laser wavelength converter of the present invention, a condensed position of the infrared light in the wavelength conversion element is deviated from a position assumed to be optimal when the influence of the generated heat is ignored. Consequently, crystal destruction is suppressed, a high-efficiency wavelength conversion is enabled and high-output wavelength converted light exceeding several watts, which was difficult to attain in conventional wavelength conversion elements, is attained.
