Essential tool for instantly converting between wavelength, energy, frequency, and time period scales in laser physics.

Pulse Bandwidth

Δλ (nm)
Transform Limit: 0 fs
Converts spectral bandwidth (FWHM) to the shortest possible pulse duration (Transform Limit) based on pulse shape.

SFG / OPO

Idler / DFG: 0 nm
Calculates energy conservation for nonlinear mixing processes: 1/λ_pump = 1/λ_signal + 1/λ_idler.

Gaussian Beam

Rayleigh Range (Zr): 0 mm
Radius at Z: 0 µm
Calculates beam spot size evolution along propagation direction for a fundamental Gaussian mode.

Slab Displacement

Lateral Shift: 0 mm
Computes the lateral beam displacement caused by transmission through a tilted transparent parallel plate.

Grating Calculator

Diffracted Angle: 0 °
Uses the grating equation to find the diffraction angle for a specific order and wavelength.

Material Dispersion

Index (n): 0.000
GVD (k''): 0 fs²/mm
Estimates Refractive Index and Group Velocity Dispersion (GVD) using Sellmeier coefficients at the current wavelength.

Broadening

Output Duration: 0 fs
Calculates temporal pulse stretching due to GVD in the selected material (assumes transform-limited Gaussian input).

B-Integral

Accumulated Phase: 0 rad
Calculates the accumulated nonlinear phase shift (B-integral) to estimate self-focusing risks.

Professional Usage Guide

Welcome to Photonics Multi-Calculator Pro. This suite is engineered for rapid estimations in ultrafast and nonlinear optics labs.

  • Unit Sync: Changing one value in the Unit Converter automatically updates all others.
  • Material Data: Dispersion calculations use Sellmeier equations for common optical glasses.
  • Safety: Always verify calculations with rigorous simulations for critical high-energy laser systems.
