摘要： A laser light flux is divided and synthesized so that its light intensity distribution is changed from a Gaussian distribution to a non-Gaussian distribution. When a laser light flux having a Gaussian distribution is irradiated onto a dividing prism, it is divided into a left part and a right part which are refracted right and left inversely from each other. When the right and left parts are incident on a synthesizing prism, they are refracted again and travel to be overlapped with each other on a recording medium. The light intensity distribution on a segment at the apex of the synthesizing prism is weaker at the central part and stronger at the peripheral part. This is because the light fluxes resulting from the division are inverted in their position so that the central part of the Gaussian distribution is separated left and right while the peripheral part with a weaker light intensity is centered.

摘要翻译： 激光光束被分割和合成，使其光强分布从高斯分布变为非高斯分布。 当具有高斯分布的激光束被照射到分割棱镜上时，它被分成左右折射，左右折射。 当左右部分入射到合成棱镜上时，它们被再次折射并在记录介质上相互重叠。 合成棱镜顶点的光束强度分布在中心部分较弱，周边部分强度分布较强。 这是因为由分割产生的光束在其位置反转，使得高斯分布的中心部分左右分离，而具有较弱光强度的周边部分居中。
