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.

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.
摘要翻译：存在在使用激光的二维图像显示装置中发生的称为斑点噪声的干扰噪声的问题，尽管通过使用多波长光源可以减少散斑噪声，但是不存在适用的绿色光源。本发明采用作为激光活化物质的稀土掺杂光纤的Yb掺杂包层泵浦光纤（103），与使用氧化物晶体的情况相比，可以显着提高荧光光谱的峰值，并且可以增加振荡波长的变化宽度。此外，由于稀土掺杂光纤被用作光纤放大器而不在其两端提供激光反射镜，所以在常规器件（其中氧化物晶体被用作激光介质）中所需要的谐振器长度的控制），从而实现高速波长控制，从而在安装在二维图像显示装置上时散斑噪声降低。
