🔴 Laser Linewidth & Bandwidth Calculator
Calculate laser spectral linewidth and frequency bandwidth parameters
📊 Linewidth & Bandwidth Formula
Δν = cΔλ/λ² = Δω/(2π) = 1/(2πτ)
Where Δν is frequency bandwidth, Δλ is wavelength linewidth, Δω is angular frequency bandwidth, τ is coherence time

💡 Tips & Information
- Linewidth is the spectral width of the laser emission
- Narrower linewidth = longer coherence length
- Single-mode lasers have very narrow linewidths
- Coherence time τ = 1/(πΔν) for Gaussian lineshape
- Quality factor Q = ν₀/Δν where ν₀ is central frequency
