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

The length of a laser resonator determines the laser’s resonator modes, or the electric field distributions that cause a standing wave in the cavity.

Laser induced damage threshold (LIDT) denotes the maximum laser fluence an optical component can withstand with an acceptable amount of risk.

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

Understanding Gaussian beam propagation is critical for understanding laser systems because many lasers are assumed to have Gaussian profiles.

Testing laser induced damage threshold (LIDT) is not standardized, so understanding how your optics were tested is critical for predicting performance.

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

Highly reflective (HR) coatings are applied to optical components to minimize losses when reflecting lasers and other light sources.

Subsurface damage in optical components can lead to increased absorption and scatter, reducing system performance.

Inhomogeneity and scatter from inclusions and bubbles in optical components can lead to worse performance, especially in laser optics applications.

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

The short pulse durations of ultrafast lasers make them interact with optical components differently, impacting the optic’s laser damage threshold.

Anti-reflection (AR) coatings are applied to optical components to increase throughput and reduce hazards caused by back-reflections.

Laser induced damage threshold (LIDT) of optics is a statistical value influenced by defect density, the testing method, and fluctuations in the laser.

Liquid lenses have many features, are small in size, and adjust focus quickly to adapt to objects located at various working distances. Learn more at Edmund Optics.

The Strehl ratio of an optical system is a comparison of its real performance with its diffraction-limited performance.

The thermal properties of optical substrates including the CTE, dn/dT, and thermal conductivity are critical for predicting real-world performance

Optical coatings are used to influence the transmission, reflection, or polarization properties of an optical component.

Metrology is critical for ensuring that optical components consistently meet their desired specifications, especially in laser applications.

Learn about specifications that should be considered when using cylinder lenses, including power axis wedge, plano axis wedge, and axial twist at Edmund Optics.

Dispersion is the dependence of the phase velocity or phase delay of light on another parameter, such as wavelength, propagation mode, or polarization.

The surface quality of optical components the scattering off of its surface, which is especially important in laser optics applications.
