Pulse width modulation (PWM), or pulse-duration modulation (PDM), is a method of reducing the average power delivered by an electrical signal, by effectively chopping it up into discrete parts. The average value of voltage (and current) fed to the load is controlled by turning the switch between supply and load on and off at a fast rate. Define laser pulse duration.

A familiar example of PDM is the International Morse Code, used in ship-to-shore communications, amateur radio, and certain other forms of radiotelegraphy. The time during which the laser output pulse power remains continuously above half its maximum value. It is the ‘work’ part of the spark cycle, when the current flows and work is done only during this time. They are commonly referred to as ultrafast events. Here, as the name suggests, the width of the pulse is varied in proportional to the amplitude of the signal.

The terms "short pulse" and "ultrashort pulse" are a bit general--typically 200 picoseconds down to femtosecond level durations--but when the pulse length becomes this short, material removal becomes a function of vaporization or sublimation rather than absorption. These terms are often confused or used interchangeably, when they are actually three different ways of measuring an electrical signal. Category: light pulses.
