A frequency modulation is then imposed of the laser beam to produce frequency sidebands which are separated from the carrier by exactly one cavity free spectral range (FSR). These pass unchanged through the cavity unless an ...
WebIn document Further development of NICE-OHMS (Page 78-85) Inpublication I, NICE-OHMS was realized in a setup which was based on a distributed-feedback (DFB) laser (NEL, NLK1C6DAAA). The wavelength of the laser was tunable by temperature between 1549 nm to 1555 nm. The fast current tuning, with a bandwidth of around 700 kHz, …
