Continuous-wave lasers are a type of laser that emits a constant beam of light without interruption. Unlike pulsed lasers, which release energy in short bursts, continuous-wave lasers provide a steady output, making them ideal for applications requiring consistent illumination or energy delivery. They are commonly used in fields such as telecommunications, medical treatments, and industrial processes. These lasers operate by maintaining a continuous flow of energy in the lasing medium, which can be a gas, liquid, or solid. Popular examples include helium-neon lasers and diode lasers, both of which are widely utilized for their reliability and efficiency in various technological applications.
