Coherence L-t Calculator

Coherence L-t Calculator is a small but super handy tool that helps you figure out the coherence length and time of a light source. Pretty cool, right?

What is Coherence Length and Time?

First off, let’s break it down. The coherence length is how far the waveform keeps a steady phase, or how far light travels during its coherence time. Speaking of coherence time, that’s just how long the light's waveform sticks to its phase.

How It Works

This app works with info you provide, like the medium’s refractive index and the light source's bandwidth in terms of wavelength and peak wavelength. Once you enter your data, you can choose to calculate either:

• The coherence time (in nanoseconds)


• The coherence length (in nanometers)

You can do this for both Gaussian and Lorentzian spectra.

Understanding Spectra Types

The Gaussian spectrum means the peak width is due to homogeneous broadening. On the other hand, if it's Lorentzian, then non-homogeneous broadening is at play.

Easy Installation

You can install this application in just seconds with a standard Windows installer. Just remember: it needs .NET Framework 4.6.2 or later before you get started.

User-Friendly Interface

The interface? Super basic! Everything you need is right there in front of you—no confusing menus or anything like that. To calculate coherence length and time, all you have to do is install it, open it up, and type in your data into the three fields at the top of the window.

Why Use Coherence L-t Calculator?

The Coherence L-t Calculator might not have flashy graphics, but it gets the job done perfectly! It lets anyone quickly calculate the coherence length and time of a light source without any hassle.
