Pulse duration or pulse width is typically measured in which unit?

Pulse duration or pulse width is usually measured in microseconds (μs), as this unit accurately captures the short time intervals associated with laser pulses and other rapid events in various technical fields. Pulses, particularly in laser applications, often have durations that are on the order of millionths of a second, making microseconds the preferred measurement for precision and clarity in describing the timing characteristics of laser emissions.

While seconds (s), milliseconds (ms), and hours (h) can also be units of time, they do not provide the granularity needed when discussing laser pulse durations, which typically require measurements at a much smaller scale to adequately represent their rapid sequence of firing. Therefore, microseconds is the unit that most appropriately corresponds with typical pulse durations in this context.
