There are many applications of lasers in which the beam profile technology is of critical importance. When the beam profile is important, it is usually necessary to measure it to ensure that the suitable profile exists. For some lasers and applications, this may be necessary only during the design and fabrication phase of the laser. In other cases, it is necessary to monitor the laser profile continuously during the laser operation. For example, scientific applications of lasers often push the laser to its operational limits and continuous or periodic measurement of the beam profile is necessary to ensure that the laser is still operating as expected. Some industrial laser applications require periodic beam profile monitoring to liquidate scrap produced when the laser degrades. In other applications, such as some medical uses of lasers, the practitioner has no capability to tune the laser, and the manufacturers measure the beam profile in the design phase to ensure that the laser provides reliable performance at all times.
The temporal nature of a laser beam enables it to vary from a continuous wave to an extremely short pulse providing very high power densities. The coherence of a laser enables it to travel in a narrow beam with a small and well-defined divergence or spread. This allows a user to define exactly the area illuminated by the laser beam technology. Because of coherence, a laser beam can also be focused to a very small and intense spot in a highly concentrated area. This concentration makes the laser beam useful for many applications in physics, chemistry, the medical industry, and industrial applications. Laser beams technology unique irradiance profile gives it very significant characteristics. The beam profile is the pattern of irradiance that is distributed across the beam or its cross-sectional irradiance profile.
Examples of two different types of ideal laser beams technology for different purposes are a Gaussian and a flat top beam. A Gaussian beam allows the highest concentration of focused light, whereas a flat top beam allows for very uniform distribution of the energy across a given area.
