Schematic of conventional wave versus micropulse laser duty cycle. a) Continuous wave laser uses a continuous beam of laser energy with a duty cycle of 100% (eg, laser beam present for 2000μs of a 2s period). b) Micropulse laser uses short intermittent bursts of laser energy, with individual pulses present for only a minority (eg, laser pulses for 200μs of a 2s period) of the laser on time, for duty cycle of 10%.
