Description

The image is a diagram that shows the energy flow in a laser. The diagram is divided into three sections, each representing a different stage of the energy flow. The first section shows the energy source, which is a light source. The second section shows the energy transfer, which is the process of converting light energy into electrical energy. The third section shows the energy output, which is the laser beam that is emitted from the device. The diagram also includes several red dots, which are likely to represent the energy levels at different points in the process. The dots are scattered throughout the image, with some located near the energy source, others near the energy transfer, and a few near the energy output.
