A laser irradiation tip has a main body and a tip end portion. The main body is connected with a handpiece and irradiating therapeutic laser with high absorbability in water. The tip end portion being connected with the main body. The main body of the laser irradiation tip has an optical fiber for guiding the therapeutic laser, a water flow path, and an air flow path in a parallel manner. The tip end portion of the laser irradiation tip has a connection portion with the main body, a water guide path communicated with the water flow path of the main body, an air guide path communicated with the air flow path of the main body, a fiber guide portion capable of inserting a tip side portion of the optical fiber, and a mixing chamber of water and air.

A dental laser radiation chip includes an optical fiber including a fiber center section having a core and a clad and also including a jacket for covering the fiber center section. The dental laser radiation chip radiates a laser light having a wavelength of around 3 &#x3bc;m. A tip section of the dental laser radiation chip has a shape of frustum tapering forward in an axial direction. The shape of frustum includes a tip face from which forward laser light is to be radiated forward in the axial direction and an inclining side face from which side laser light is to be radiated in a radial direction with respect to the axial direction. The tip face is mirror-surface-finished to have a surface roughness of 0.008 &#x3bc;m. The inclining side face is rough-surface-finished to have a surface roughness of 0.4 &#x3bc;m.
