What characteristic is associated with a chopped or gated laser beam?

A chopped or gated laser beam is characterized by its ability to pulse, alternating between an "on" state and an "off" state. This pulsing action alters the power level delivered by the laser, creating bursts of energy rather than a continuous stream. The modulation of the laser beam into distinct intervals allows for controlled application of energy, which can be beneficial in various therapeutic and clinical settings.

When manipulating the laser in this manner, practitioners can achieve specific therapeutic outcomes, such as reducing potential overheating of tissue and improving the effectiveness of treatment through targeted energy delivery. This approach contrasts with other methods like continuous modulation, which maintains a steady output without interruption, and high energy density, which refers to the concentration of energy within a confined space rather than the pulsing nature of the beam.
