In terms of laser technology, what does the term 'pulse' typically refer to?

The term 'pulse' in laser technology specifically refers to a burst of energy delivered over a short duration. This means that instead of emitting a continuous beam of energy, a pulsed laser emits energy in quick, concentrated bursts, allowing for precise control over the amount of energy delivered in each pulse. This can be particularly beneficial in applications such as medical procedures or material processing, where the ability to target energy delivery to specific areas at specific times can improve effectiveness while reducing collateral damage to surrounding tissues or materials.

Pulsed lasers can be characterized by their pulse duration and repetition rate, which influence their applications. For instance, shorter pulses can minimize thermal effects, making them suitable for more delicate surgical procedures or treatments.

In contrast, a continuous stream of energy does not fit the definition of a pulse, as it does not involve discrete packets of energy but rather a steady output. The other options related to energy absorption and methods of measuring power output are different concepts altogether, as they do not define what a pulse is within the context of laser operation.
