Use this laser calculation or lookup for a first-pass optics, pulse, beam, gain-medium, diode, fiber, or safety comparison under explicitly stated wavelength and operating conditions.

Donor power (W)

Excitation power carried by the O2(¹Δ) donor state.

Laser power (W)

Measured 1315 nm laser output power.

Compute chemical oxygen–iodine laser energy-transfer efficiency from donor chemical power and 1315 nm output power with the photon-energy quantum cap. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Efficiency (%)

Laser over donor power as a percentage.

Quantum cap (%)

Photon-energy ceiling 1270/1315.27 as a percentage.

Note

Interpretation of the efficiency gap.

• Laser behavior depends on wavelength, mode, coherence, pulse shape, beam quality, cavity and optical losses, material data, temperature, alignment, nonlinear effects, damage thresholds, and measurement definitions. Lookup values are not substitutes for current device data or laser-safety analysis.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Verify constants and limits with primary literature and manufacturer data, propagate tolerances, model the complete optical train, and apply the relevant laser safety standard.

• Excimer and F2 Gas Mixture Table

  Look up an excimer or molecular-fluorine laser wavelength and photon energy, with a reminder that gas-fill life depends on the complete laser system.

• Facet Coating Power Split

  Split the internal laser power between the two facets from their reflectivities, either coated or a bare cleaved GaAs facet.

• HeNe Cavity Length Design

  Compare a He-Ne 632.8 nm optical cavity's c/(2L) axial-mode spacing with an explicit gain-bandwidth assumption; this does not guarantee mode-hop-free operation.
