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.

Wavelength (nm)

Centre wavelength of the Ti:sapphire gain band.

n0

Refractive index of Ti:sapphire.

n2 (cm²/W)

Nonlinear refractive index.

Available peak power (kW)

Peak power available inside the resonator.

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

P_cr (W)

Critical power for self-focusing.

KLM feasible

Whether Kerr-lens mode locking can start and hold.

Margin factor

Ratio of available to critical peak power.

Tuning ranges

Typical mirror-set tuning ranges for reference.

• 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 Soft-Aperture Overlap Check

  Compare continuous-wave and mode-locked Ti:sapphire mode overlap with a Gaussian pump as a soft-aperture screening check, without claiming full cavity stability.

• CEO f-to-2f Octave Check

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

• Yb-Fiber Power Scaling Timeline

  Look up the latest entry at or before a year in this curated set of representative single-mode Yb-fiber power milestones. It is a compact engineering timeline, not an exhaustive record-claim database.
