||This course covers key parameters that describe the operational characteristics of lasers including small signal gain, saturation, threshold gain, and power out. The five specific classes of lasers are introduced: atomic gas, molecular gas, liquid, solid-state, and semiconductor. Operation and characteristics of optical detectors: photon and thermal are explored. Photonics enabled technologies used in various fields including fiber optic communications, photonic devices for imaging, display and storage, principles and applications of holography, manufacturing, forensic science and homeland security, biomedicine, environmental monitoring, and optoelectronics are discussed. Hands-on lab activities with lasers are conducted, as well as, computational labs in which important laser characteristics are figured using algebraic formulas.
