Abstract :
A simple method is proposed for producing a quasiderivative signal of Fabry-Perot resonance with respect to a laser frequency. The quasiderivative signal has been obtained by the subtraction of two Fabry-Perot transmission signals with slightly different resonance frequencies. This technique can be employed in the fast electrical feedback for laser frequency stabilisation.
