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

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.

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.

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

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.

Learn the key parameters that must be considered to ensure you laser application is successful. Common terminology will be established for these parameters.

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.

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

Learn why the bulk laser-induced damage threshold (LIDT) of glass is significantly different than the LIDT optical components with coatings, such as AR thin films.

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

Understanding the polarization of laser light is critical for many applications, as polarization impacts reflectance, focusing the beam, and other key behaviors.

Overspecifying optical losses in laser systems will not further improve your performance or reliability, but it could cost you additional money and/or time.

Laser Induced Damage Threshold describes the maximum quantity of laser radiation an optic can take before damaging. Learn more at Edmund Optics.

Understanding the most commonly used laser optics materials will allow for easy navigation of EO’s wide selection of laser optics components.

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

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
