PCSEL Aperture Intensity
Calculate PCSEL aperture area and average output intensity.
Description
Circular-aperture average intensity divides total output power by aperture area.
Circular-aperture average intensity divides total output power by aperture area. This does not imply uniform local intensity.1
Calculate PCSEL aperture area and average output intensity.
When to use PCSEL Aperture Intensity
Use this tool to calculate PCSEL aperture area and average output intensity.
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 PCSEL Aperture Intensity 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 outputPowerWatts, apertureDiameterMeters using the field table and calculation rules, then run the tool.
- Read apertureAreaSquareMeters, averageIntensityWPerM2. 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 |
|---|---|---|---|
| outputPowerWatts | Output power (W) | number; minimum: 0 | Required |
| apertureDiameterMeters | Aperture diameter (m) | number; minimum: 0 | Required |
Enter nonnegative output power and positive aperture diameter in meters. Return m² and W/m².
area=π(diameter/2)²; averageIntensity=power/area Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| apertureAreaSquareMeters | Aperture area (m²) | number; minimum: 0 |
| averageIntensityWPerM2 | Average aperture intensity (W/m²) | number; minimum: 0 |

}Limitations and assumptions
No PCSEL field profile, thermal loading or peak-intensity model is included.
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.
Alternative or Complementary methods
Use Welding Mode Threshold: Compare weld intensity with a caller-supplied keyhole transition threshold. For a complementary task, use Spatial-Filter Pinhole: Calculate an Airy-diameter spatial-filter pinhole size with relay magnification.
