How Thulium/Holmium Water Absorption Lookup works
Compare nominal 1908 nm thulium-fiber and 2090 nm holmium:YAG sources using tabulated water absorption and the corresponding 1/µa penetration estimate. 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
- Wavelength (nm)
- Nominal source wavelength.
- Source type
- Laser gain-medium family.
- Water absorption (cm^-1)
- Tabulated water absorption coefficient at the wavelength.
- Penetration depth (µm)
- Water-only optical penetration estimate 1/µa.
- Note
- Scope and safety limitation for interpreting the value.
Limitations and assumptions
- 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.
Alternative or Complementary approaches
Verify constants and limits with primary literature and manufacturer data, propagate tolerances, model the complete optical train, and apply the relevant laser safety standard.
