Diode laser frequency stabilisation
Stabilisation of the frequency of a diode laser with an external resonator to an atomic absorption line In this illustrative application, we explore the process of stabilising the frequency of a tunable diode laser using an external resonator, specifically designed to interact with an atomic absorption line. In this application, the frequency of a tunable laser is stabilised with the help of a reference cell, or a gas reference cell. Suitable lasers can include tunable diode lasers, Ti:Sa or dye lasers. The aim is to set the laser frequency to a value at which the sample has maximum absorption (or…
