Pulse Power Measurement: Measuring Instantaneous Power of a Short Pulse

You can now measure high average powers using moderate power sensors, using a new feature in the StarBright meter called “Pulse Power Measurement”. Thermopile sensors are often used to measure single shot pulse energy; the instrument can easily calculate instantaneous pulse power from this if it knows the pulse width (since power = pulse energy / pulse width). With the StarBright set to “Pulse Power” mode (supported from StarBright firmware version 1.30), the user enters the length of the pulse, fires the pulse, and StarBright then displays the instantaneous power during the pulse. Details are in the new version of the StarBright User Manual, now available on the website.
