Abstract: Provided is an external resonance-type laser device with high wavelength conversion efficiency in which a nonlinear optical crystal is disposed outside of a resonator. The laser device includes a laser generation device configured to generate high-intensity laser light, a nonlinear optical crystal on which the high-intensity laser light generated by the laser generation device is incident and which is configured to generate a second harmonic wave light, and a different-element-fluxless-grown nonlinear optical crystal on which the second harmonic wave light generated by the nonlinear optical crystal is incident and which is configured to generate a fourth harmonic wave light. In the laser device, the different-element-fluxless-grown nonlinear optical crystal is not damaged even when high-intensity laser light of 100 MW/cm2 or more is incident.

Abstract: Provided is a clip structure which can prevent components from falling off an attaching body or an attached body with a simple structure. Further provided is a holding structure for an internal member of a vehicle which can prevent the components from falling off an exterior member or an interior member with a simple structure. A clip assembly (11) includes a first clip having a clip (34) attached to a bracket (25), and a joint (36) as a removable portion connected to the clip 34; and a pin (38) as a second clip connected to the joint (36) and sandwiching a roof head lining (14) between the pin (38) and the joint (36). A holding load (F5) for releasing connection between the clip (34) and the joint (36) is sufficiently small compared to a holding load (F6) for releasing connection between the joint (36) and the pin (38).
