Define pulse duration as used in optic applications. Why is this definition preferred?

The Pulse duration is nothing but the Pulse width or pulse length and it can be varied in huge range.In optical application like laser diodes the pulses with duration down to few nanoseconds and even to hundred picoseconds.For some mode-locked lasers generates Pulses with duration between 5fs and hundreds of pico seconds.
