الانبعاث التلقائي |  Spontaneous emission

22 أبريل 2020


عند وجود إلكترون في مستوى طاقة عالٍ، يميل إلى الهبوط إلى مستوى طاقة منخفض أكثر استقراراً، وأثناء عملية الهبوط يطلق الإلكترون كمية من الطاقة تلقائياً، ويمكن لهذه الطاقة أن تكون شعاع الليزر، وتُسمَّى هذه العملية بالانبعاث التلقائي لليزر، وفيها لا يتسم الليزر بالترابط، ولا يخرج في الاتجاه نفسه كل مرة.
