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.

Short edge (nm)

Short-wavelength edge of the broadened comb.

Long edge (nm)

Long-wavelength edge of the broadened comb.

Check whether a frequency-comb span supports f-to-2f carrier-envelope-offset stabilization via the octave criterion. 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]

Octave ratio

Long-to-short wavelength ratio.

Octave spanning

True when the ratio reaches 2 (one octave).

Note

Stabilizer guidance for the span.

• 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.

• Ti:Sapphire KLM Prerequisite Check

  Check whether the intracavity peak power clears the Kerr self-focusing critical power that Ti:sapphire KLM mode locking requires.

• Attosecond Streaking Window

  Compare an XUV burst duration with the IR half-cycle λ/(2c) while keeping this timing screen separate from streaking phase-retrieval feasibility.

• Bar Smile Pointing Budget Checker

  Translate the smile (emitter curvature) of a diode bar into far-field pointing error after collimation and check it against the budget.
