The short pulse durations of ultrafast lasers lead to broad wavelength bandwidths, making ultrafast systems especially susceptible to dispersion and pulse broadening.
Ultrafast Lasers – The Basic Principles of Ultrafast Coherence
Advances in laser technology have made it possible to produce pulses ranging from a few femtoseconds to tens of attoseconds. Learn more at Edmund Optics.
Ultrafast highly-dispersive mirrors are critical for pulse compression and dispersion compensation in ultrafast laser applications, improving system performance.
Surface roughness describes how a shape deviates from its ideal form. This is critical for controlling light scatter in laser devices and other optical systems.
Understanding the most common laser sources, modes of operation, and gain media provides the context for selecting the proper laser for your specific application.
Not all optical components are tested for laser-induced damage threshold (LIDT) and testing methods differ, resulting in different types of LIDT specifications.
Dispersion is the dependence of the phase velocity or phase delay of light on another parameter, such as wavelength, propagation mode, or polarization.
Laser induced damage threshold (LIDT) of optics is a statistical value influenced by defect density, the testing method, and fluctuations in the laser.
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.
Learn the key parameters that must be considered to ensure you laser application is successful. Common terminology will be established for these parameters.
Power density, energy density, fluence, and irradiance are often incorrectly used in laser optics applications. Learn the correct definitions and usage.
A Guide to (Not Over) Specifying Losses in Laser Optics
Overspecifying optical losses in laser systems will not further improve your performance or reliability, but it could cost you additional money and/or time.
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.
Testing laser induced damage threshold (LIDT) is not standardized, so understanding how your optics were tested is critical for predicting performance.
