A nerve site having an area of about 2 cm 2 of the mouse was separately irradiated with only the first and second laser beams for 30 seconds. For each irradiation, the stimulus reaction rate and the change in body temperature after irradiation were measured with an electromyography. As a result, when the polarization direction of the second laser light is aligned with the running direction of the nerve fibers of the mouse (polarization angle of 0 degree) and when the polarization direction is perpendicular to this (polarization angle of 90 degrees), the polarization angle is 0 degree.
