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.
The short pulse durations of ultrafast lasers lead to broad wavelength bandwidths, making ultrafast systems especially susceptible to dispersion and pulse broadening.
Learn the key parameters that must be considered to ensure you laser application is successful. Common terminology will be established for these parameters.
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.
