GM Cross-Section Converter
Convert Goeppert–Mayer units to two-photon cross-section units.
Description
Goeppert–Mayer units express two-photon absorption cross section.
Goeppert–Mayer units express two-photon absorption cross section. Converting cm⁴ to m⁴ introduces an additional factor of 1e−8.1
Convert Goeppert–Mayer units to two-photon cross-section units.
When to use GM Cross-Section Converter
Use this tool to convert Goeppert–Mayer units to two-photon cross-section units.
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 GM Cross-Section Converter 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 crossSectionGm using the field table and calculation rules, then run the tool.
- Read crossSectionCm4SPerPhoton, crossSectionM4SPerPhoton. 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 |
|---|---|---|---|
| crossSectionGm | Two-photon cross section (GM) | number; minimum: 0 | Required |
Enter nonnegative GM value. Return the two cross-section unit values.
1 GM=1e−50 cm⁴·s/photon=1e−58 m⁴·s/photon Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| crossSectionCm4SPerPhoton | Cross section (cm⁴·s/photon) | number; minimum: 0 |
| crossSectionM4SPerPhoton | Cross section (m⁴·s/photon) | number; minimum: 0 |

}Limitations and assumptions
No cross-section measurement, wavelength dependence or two-photon rate is calculated.
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.
