Abstract:
1. A laser device for medical treatment system, comprising at least a plurality of laser beam emitting sources, a laser beam multiplexing means for superimposing the laser beams emitted from said laser beam emitting sources, and a beam mixing means where the laser beams from said laser beam multiplexing means enter and which is an optical fiber for reflecting the laser beams by multireflection inside said optical fiber, and a condenser lens for focusing and entering the laser beams from said beam mixing means to a second optical fiber for propagation wherein said beam mixing means emits the laser beams so that the laser beam emitted from said laser device has a relation of 10≦M 2 ≦22, where W·Θ=M 2 λ/π, M is a parameter to express the quality of the laser beam W is a beam waste, Θ is a spreading angle, and λ is a wavelength of the laser beam.
