Noise-Like Pulse Duty Factor
Calculate noise-like burst duty factor, burst energy, and in-burst average power.
Description
Noise-like burst budgeting separates pulse-train average power from average power during a burst.
Noise-like burst budgeting separates pulse-train average power from average power during a burst. Burst duty factor links the two.1
Calculate noise-like burst duty factor, burst energy, and in-burst average power.
When to use Noise-Like Pulse Duty Factor
Use this tool to calculate noise-like burst duty factor, burst energy, and in-burst average power.
Prepare the optical measurements, geometry, fitted coefficients or caller-selected thresholds requested. Confirm wavelength, radius/diameter, pulse-width, angle and unit conventions before running the calculation.
How to use Noise-Like Pulse Duty Factor and understand its results
- Prepare the optical measurements, geometry, fitted coefficients or caller-selected thresholds requested. Confirm wavelength, radius/diameter, pulse-width, angle and unit conventions before running the calculation.
- Enter noiseBurstDurationSeconds, repetitionRateHertz, averagePowerWatts using the field table and calculation rules, then run the tool.
- Read dutyFactor, pulseEnergyJoules, inBurstAveragePowerWatts. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| noiseBurstDurationSeconds | Noise-like burst duration (s) | number; minimum: 0 | Required |
| repetitionRateHertz | Repetition rate (Hz) | number; minimum: 0 | Required |
| averagePowerWatts | Average power (W) | number; minimum: 0 | Required |
Enter positive burst duration/rate and nonnegative average power. Return duty factor, joules per burst and in-burst average watts.
duty=duration×rate; energy=averagePower/rate; burstPower=averagePower/duty Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| dutyFactor | Burst duty factor | number; minimum: 0 |
| pulseEnergyJoules | Burst energy (J) | number; minimum: 0 |
| inBurstAveragePowerWatts | Average power within burst (W) | number; minimum: 0 |

}Limitations and assumptions
Duty is not constrained below one. Internal subpulses and instantaneous peak power are not resolved.
Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
