What are the two basic types of laser systems?

The two basic types of laser systems are classified as continuous wave (CW) and pulsed lasers based on their operational mode. Continuous wave lasers emit a constant beam of light, meaning they provide a steady output over time. This type of operation is suitable for applications requiring a smooth and uninterrupted output of laser energy, such as in some medical and industrial applications.

On the other hand, pulsed lasers generate energy in short bursts, creating high-intensity light for brief periods. This pulsed output is highly advantageous for applications needing high peak power, such as laser cutting, precision machining, and certain medical treatments. The distinction between these two types of operational modes is fundamental to understanding how different laser systems can be utilized effectively in various technological fields.

While other classifications, such as solid-state versus gas lasers or diode versus fiber lasers, are important in understanding specific laser technologies, they are not foundational in the same way that CW and pulsed operations define the basic types of laser systems. Therefore, recognizing the CW and pulsed distinction is key to grasping the core operational principles of laser technology.
