A laser collimator works by converging a divergent beam, by one or a group of positive focal length lenses, to make the beam be collimated to the optical axis. For example, if the beam emitting from a fiber laser tip is small and divergent at an angle of a few degrees, the collimator can collimate the beam to be larger in diameter but with a very small divergent angle.

A typical laser beam expander consists of two lenses placed a certain distance apart, with the distance between the lenses being equal to the sum of their focal lengths. The first lens diverges the laser beam to a larger diameter, and the second lens then collimates the enlarged beam to be parallel. The amount of expansion is determined by the ratio of the focal lengths of the two lenses.

Laser beam expanders are commonly used in laser machining, laser cutting, and laser marking applications, where a precise and focused laser beam is required. They can also be used in scientific research, such as in laser spectroscopy or microscopy.
