A nuclear pumped laser (NPL) is a type of laser that utilizes the energy released from a nuclear reaction to pump the laser medium, thereby generating coherent light. This innovative technology harnesses the high-energy gamma radiation emitted from radioactive materials, typically from a nuclear reaction, to excite the atoms or molecules in the laser medium. ### Basic Principles: 1. **Pumping Mechanism**: In traditional lasers, electrical or optical energy is used to excite the atoms in the gain medium.
