Quantum cascade lasers (QCLs) are IR lasers that utilize tens or hundreds of quantum wells to decouple the emission wavelength from the bandgap energy.
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.
Understanding the most common laser sources, modes of operation, and gain media provides the context for selecting the proper laser for your specific application.
Laser Polarization: The Importance of Polarization in Laser Applications
Understanding the polarization of laser light is critical for many applications, as polarization impacts reflectance, focusing the beam, and other key behaviors.
The short pulse durations of ultrafast lasers lead to broad wavelength bandwidths, making ultrafast systems especially susceptible to dispersion and pulse broadening.
Not all optical components are tested for laser-induced damage threshold (LIDT) and testing methods differ, resulting in different types of LIDT specifications.
Power density, energy density, fluence, and irradiance are often incorrectly used in laser optics applications. Learn the correct definitions and usage.
Learn the key parameters that must be considered to ensure you laser application is successful. Common terminology will be established for these parameters.
UV grade fused silica is ideal for UV and visible applications, but IR grade fused silica has better transmission in the IR due to a lack of OH- impurities.
Diamond-Like Carbon and High-Durability AR Coatings
Diamond-like carbon (DLC) coatings are a type of highly durable, anti-reflective optical coating ideal for defense applications and other harsh environments.
Converting a Gaussian laser beam profile into a flat top beam profile can have numerous benefits including minimized wasted energy and increased feature accuracy.
Laser optics high reflectivity mirrors meet exceptional specifications that Edmund Optics' competitors often fail to meet. Learn more at Edmund Optics.
Ultrafast highly-dispersive mirrors are critical for pulse compression and dispersion compensation in ultrafast laser applications, improving system performance.
