  • What is Nonlinear Optics?
    Article - 3 Mar 2023
    Nonlinear optics is the branch of optics that studies the properties and the interaction of light in a medium where the polarization density interacts nonlinearly with the electric field of light.
  • Int. Women's Day Spotlight: Inspirational Figures in the Photonics Industry
    Article - 2 Mar 2023
    To celebrate International Women's Day this year on AZoOptics across its different themes, we spoke with three leading researchers about their work in the domain of optics and photonics and their...
  • What is Photothermal Spectroscopy?
    Article - 14 Feb 2023
    A type of optical analytic technique called photothermal spectroscopy is a powerful tool to study heat that is produced as a result of light absorption in a sample that has been exposed to radiation.
  • Recent Research on Quantum Cascade Lasers
    Article - 10 Feb 2023
    Quantum cascade lasers are a type of semiconductor laser that typically emit in the mid-infrared region (~ 4 µm to 10 µm). They are somewhat unusual in comparison to other laser systems in terms of...
