Abstract: The present invention provides a light irradiation method using a pulse laser, which can be applied to technology of PDD and/or PDT, and a system for treating a tumor, which has an enhanced tumoricidal effect. A light irradiation method of irradiating a cell into which a photosensitive compound capable of generating singlet oxygen has been incorporated with a pulse laser having a wavelength within a Soret band is provided. The pulse width of the pulse laser can be set to 100 psec or less, and the wavelength can be set to 405±10 nm. As the photosensitive compound capable of generating singlet oxygen, an agent for photodynamic therapy (PDT) or an agent for photodynamic diagnosis (PDD) can be used.

Abstract: [Object] There is provided .a medical laser irradiation device and a medical laser irradiation method, both of which are capable removing plaque adhering to the angioendothelium more safely using laser light. [Solution] A medical laser irradiation device according to the present disclosure includes a first laser light source configured to emit a first laser light having a wavelength band that is selectively absorbed by plaque existing inside a blood vessel of a living body; a second laser light source configured to emit a second laser light having a wavelength band that is selectively absorbed by the plaque calcified and existing inside the blood vessel; and an optical fiber configured to coaxially guide the first laser light and the second laser light, and at least a part of which is inserted into the blood vessel.
