激光(Laser)是“Light Amplification by Stimulated Emission of Radiation”的首字母縮寫,中文意為“受激輻射的光放大”。它是一種通過受激輻射過程産生和放大的、具有高度方向性、單色性、相幹性和高亮度的光。以下是其核心含義的詳細解釋:
核心原理:受激輻射

LASER 是 "Light Amplification by Stimulated Emission of Radiation"(受激輻射光放大)的首字母縮寫,指通過受激發射過程産生的高強度、高度聚焦且單色性(單一波長)的相幹光束。以下是詳細解釋:
激光的原理基于愛因斯坦提出的受激發射理論:
高功率激光可能損傷視網膜或皮膚,需遵守安全規範(如佩戴防護眼鏡、避免直射)。
激光是近代物理學與工程技術的裡程碑成果,其獨特性質使其成為現代科技不可或缺的工具。
