PURPOSE:To oscillate a plurality of laser lights with different wave lengths by using one laser apparatus by providing laser guide means each guiding a laser light with different wavelength oscillated from each laser element part and providing a wavelength transforming element transforming the wavelength of a laser light guided on a light path guiding one laser light. CONSTITUTION:When an electric voltage is applied between electrodes f and g of laser elements 2 and 3, the elements 2 and 3 inductively output respectively a laser light. The element part 2 irradiates a laser light with a wavelength of 630nm and the element part 3 irradiates a laser light with a wavelength of 810nm. These laser lights are applied to a tumor part through optical fibers 5 and 8 and a laser probe 11. In this case, the laser light emitted from the element part 2 and with a wavelength of 630nm is used for photochemical therapy or a guide light and the laser light emitted from the element 3 and with a wavelength of 810nm is converted into laser light with a wavelength of 405nm by means of a wavelength conversion element 10 and is used for photochemical therapy. In addition, when driving of each of laser element 2 and 3 is performed by loading to each electrode f or g individually, it can be selectively oscillated, and when they are simultaneously loaded, each laser light can be simultaneously emitted. |
