Description

The image is a diagram that shows the process of energy transfer in a laser. The diagram is divided into three sections, each representing a different stage of energy transfer. The first section shows the energy source, which is typically a power source such as a battery. The second section shows the energy transfer process, which involves the use of a laser to transfer energy to a target. The third section shows the energy output, which is typically the result of the energy transfer process. The diagram also includes a graph that shows the energy transfer efficiency, which is the ratio of the energy output to the energy input.
