What is the difference between continuous wave lasers and pulsed lasers?

Continuous wave lasers emit a constant beam of light, which means they produce a steady, uninterrupted flow of energy over time. This characteristic allows them to maintain a consistent output, making them suitable for applications that require a stable laser source. Examples of continuous wave lasers include semiconductor lasers and solid-state lasers, which are often employed in various industrial and medical applications due to their reliability and efficiency.

In contrast, pulsed lasers operate by emitting light in discrete bursts or pulses. This pulsing action creates high peak power levels for very short durations, which can be advantageous for applications such as material processing or medical treatments where precision is critical.

The statement that continuous wave lasers emit a constant beam accurately captures the essence of their operation, highlighting their key distinction from pulsed lasers.
