The width of the pulse in PPM is not important, but is usually very narrow and constant in any given PPM system.
For the Radar Case: The bandwidth of the pulse is the reciprocal of the Pulse Duration (called Pulse Width) as any filtering needs to be able to detection and follow the pulse shape and its edges. The pulse width is the AM modulation to a Fixed Frequency Carrier Frequency and the AM modulation will be greater bandwidth then the Carrier Frequency. As you are attempting to reject receiving other emissions and noise that do not match your own emissions such that your receiver is "match filtered" to your emissions, your receiver bandwidth will be at least the reciprocal of the pulse width but is lightly to be a smaller bandwidth then the reciprocal of the pulse width.
Pulse width mod, pulse amplitude mod, pulse position mod, pulse code mod.
pulse width modulation is nothing but changing on and off time period of a waveform without changing its frequency
A bioplasma is a short laser pulse of biological origin.

Explain with diagram the technique Pulse-width modulation?
Power broadening is an effect whereby the line-width of a laser is broadened by the laser intensity itself. Higher laser intensity leads to a larger line-width. This can be explained by considering the decay rate of atoms from the upper to lower laser level. As the laser intensity increases, this decay rate (which is linearly related to the line-width) increases due to stimulated emission.
Pulse width is the time in milliseconds that the injector is energized, the duty cycle is the percentage of on-time to total cycle time
