Shack-Hartmann wavefront sensors are used to test the transmitted wavefront error of laser beam expanders, predicting the real-world performance of the beam expander.

Sliding focusing mechanisms for laser beam expanders cause less beam wander than rotating focusing mechanisms, but they use more complex mechanics and are typically more expensive.

Converting a Gaussian laser beam profile into a flat top beam profile can have numerous benefits including minimized wasted energy and increased feature accuracy.

The diameter of a laser highly affects an optic’s laser induced damage (LIDT) as beam diameter directly impacts the probability of laser damage.

There are several metrics used to describe the quality of a laser beam including the M2 factor, the beam parameter product, and power in the bucket

Beam expanders can be used in reverse to decrease a laser beam's diameter, but divergence will be increased.

Learn more about the advantages of using beam expanders in laser optics applications, with examples on spot size and beam size, at Edmund Optics.

Laser beam expanders are critical for reducing power density, minimizing beam diameter at a distance, and minimizing focused laser spot size.

Learn how to navigate the many available options for shaping the irradiance profile and phase of laser beams to maximize your laser system's performance.

Many lasers are assumed to have a Gaussian profile, and understanding Gaussian beam propagation is crucial for predicting real-world performance of lasers.

Surprisingly, intentionally clipping a laser beam going through a higher magnification beam expander can be the optimal solution.
