PURPOSE:To obtain a laser device to be used for treatment of a simple hemangioma and the like by a method wherein a sectional area of a face vertical to the laser optical axis inside a pigment cell is formed to be large enough, an optical scattering layer is formed on the peripheral surface and laser light of specific pulse width and output is generated. CONSTITUTION:A pigment cell 3 as a waveguide, wherein energy supply 1 generating excitation light, whose pulse width may be at least 10 microseconds, is connected to a lamp 2 generating an electric pulse as an excitation light generating means, while having a pigment solution with a controlled temperature in its hollow part, takes a sufficiently large sectional area of the face vertical to a laser optical axis while forming a light scattering layer on the peripheral surface. Then, laser light having the pulse width of 10 to hundreds microseconds while having output more than several joules is generated. Thereby, a laser device optimal for treatment of a hemangioma can be obtained. |
