There are a wide range of general-purpose laser systems used in applications as diverse as materials processing, laser surgery, and remote sensing, but many have key parameters in common. Establishing common terminology for these parameters can prevent communication errors, and understanding them allows the laser system and components to be properly specified to meet application needs.
