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.

XUV duration (as)

XUV burst duration to retrieve.

IR wavelength (nm)

Dressing IR wavelength setting the half-cycle window.

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

Half-cycle window (as)

IR half-cycle window λ/2c in attoseconds.

Fits half-cycle

True when the burst fits inside one half-cycle.

Note

Retrieval guidance for the window.

• 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.

• 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.

• QCL Gas Fingerprint Selection Table

  Return the mid-infrared QCL emission window that targets the strongest ro-vibrational fingerprint of a common gas.

• Nd:YVO₄ vs Nd:YAG Pump Absorption Compare

  Compare the 808 nm pump absorption coefficients of Nd-doped YVO₄ and YAG for equal at.% dopings, including bandwidth trade-offs.
