Abstract
We report on the development of a transportable iodine frequency stabilized laser setup, based on compact-fibered frequency tripled Telecom laser, locked to the a10 hyperfine component of the 127I 2 line at 532.245 nm. Therefore, a tandem of Nd: YAG lasers are phase-locked to this reference laser and used for precise interferometry measurements as part of the French activities in the frame of LISA-France consortium, led by the French space agency (CNES). The frequency stability transfer from 1596 nm to the LISA nominal wavelength at 1064.49 nm is fulfilled in a simple manner [1], using the usual phase locking loop technique associated to a second harmonic generation process. The compact design of the whole setup will make it easily transportable and can be readily used on different sites.
