The wavelength conversion element converts the fundamental wave into the harmonic wave. In addition, the wavelength conversion element includes a holder holding the wavelength conversion element, wherein the wavelength conversion element has a specific region on a light output side, which is arranged so as to suppress variations in phase matching condition between the fundamental wave and the harmonic wave resulting from heat generated by absorbing the harmonic wave during a wavelength conversion.

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。

The period of the polarization reversal structure is designed so that a quasi phase matching temperature of the fundamental wave and the harmonic wave is 40° C. or higher. The heater (4) heats the wavelength conversion element (3) to a temperature at which quasi phase matching is established, and the nonlinear optical crystal contains a lithium niobate or lithium tantalate including at least any one of additives Mg, In, Zn and Sc as a main component. Thus, optical damage can be suppressed and visible light absorption attributed to ultraviolet light can be reduced.

摘要： There has been a problem that pumping light leaks from a part having a coating at the joint of a double-clad fiber added with a rare earth and a general single-mode fiber, and heat is generated partly from the fiber by this energy thus causing deterioration of the fiber. Deterioration of a fiber due to residual excitation light can be prevented by preventing residual excitation light in a double-clad fiber from exiting to a single-mode fiber, and the reliability is enhanced. Output of oscillation light can be increased because output of excitation light is not limited. Furthermore, a laser display having a high color reproducibility can be achieved by employing a light source combining a fiber laser light source and a wavelength conversion module.
