Laser diagnostics refers to a set of techniques that use lasers to analyze and measure various properties of materials and systems. This technology is widely used in fields such as medical imaging, environmental monitoring, and industrial processes. By directing a laser beam at a target, scientists can gather information about its composition, temperature, and other characteristics based on how the laser light interacts with the material. These methods are valued for their precision and non-invasive nature. For example, in medical applications, laser diagnostics can help detect diseases without the need for invasive procedures. Overall, laser diagnostics plays a crucial role in advancing research and improving technology across multiple disciplines.
