Laser Beam Expander: Parameter, Principle, and Product Selection

Laser beam expanders are designed to alter the laser beam diameter, divergence angle, and intensity distribution. They are commonly used in applications such as laser scanning, laser resonators, laser interferometry, and remote sensing to achieve functions like reducing spot energy density, decreasing beam diameter at a specific distance, minimizing focused spot size, and compensating for laser beam size. They are one of the most widely used components in laser systems.
