(Submitted on 12 Jun 2013) Abstract: Finesse is a fast interferometer simulation program. For a given optical setup, it computes the light field amplitudes at every point in the interferometer assuming a steady state. To do so, the interferometer description is translated into a set of linear equations that are solved numerically. For convenience, a number of standard analyses can be performed automatically by the program, namely computing modulation-demodulation error signals, transfer functions, shot-noise-limited sensitivities, and beam shapes.
Finesse can perform the analysis using the plane-wave approximation or Hermite-Gauss modes. The latter allows computation of the properties of optical systems like telescopes and the effects of mode matching and mirror angular positions.

Topics. Waves. Sound Description Make waves with a dripping faucet, audio speaker, or laser! Add a second source or a pair of slits to create an interference pattern.
Transport. Sample Learning Goals. You can watch water, sound, and light waves move and see how they are related. All can be represented by a sinewave.
What does this sinewave represent for these three different phenomena?. Use multiple sources with different spacing and see a changing interference pattern. Find points of constructive and destructive interference by eye, and by using the detectors. Put up a barrier to see how the waves move through one or two slits.
What sort of pattern do the slits create? How can you change this pattern?. In the light panel, predict the locations of the fringes that appear on the screen using d sin(θ) = mλ. Use the tape measure to verify your predictions. Version 1.10.

Charlotte Bond summer project 2009 The applet below illustrates the interference of optical waves in a Michelson interferometer. You can change the length of one interferometer arm and observe how the light power in the two interferometer output changes. You can also play with the reflectivity of the beam splitter or the mirrors to understand their effect on the interference. If you want to know how light fields are reflected or transmitted at an optical surface, have a look at my other applet:! In this sketch the light is depicted as waves. Using the tick box `play waves continuously' you can choose to have static or travelling waves. The amplitude of the waves represent the light power in the respective beam.
The input beam (black, coming in from the left) is split by the beam-splitter into two beams (up and right) which then move through the interferometer arms, are reflected by the so-called end mirrors and then recombine at the beam-splitter. This creates in general to output beams: one travelling to the left and one down. By changing the length of one interferometer arm the amount of power can be moved between the two output beams. The sliders can be used to change several parameters of the interferometer:. Length of second arm – This controls the position of the second mirror. Reflectivity: beam-splitter – This controls the power reflectivity of the beam-splitter. Reflectivity: first mirror – This controls the power reflectivity of the first mirror.
Interferometer Antenna
Reflectivity: second mirror – This controls thepower reflectivity of the second In gravitational wave detectors the Michelson interferometer is typically used at the so-called `dark fringe', i.e. A setup in which no light leaves the interferometer `downwards'. This can be achieved with a microscopic arm length difference of 0.25 wavelength.
Try to set the Michelson above to the dark fringe yourself. You can also find out what happens, e.g. To the dark fringe, when you change the reflectvity of the end mirrors. And of course it's worth investigating the extreme settings just to see what happens: when you set the beam-slitter reflectivity to 0 or to 1, what do you expect to see?
