Abstract :
We demonstrate a 10 GHz spectrum analyzer with MHz resolution and > 30 dB dynamic range using the spectral-hole-burning (SHB) Tm3+: YAG crystal working at 793 nm. Thanks to the fast and linear chirping capabilities of the laser used, it has a potential 100% probability of interception and a response time in the ms range. The system is compared to a previously demonstrated SHB spectral analyzer.
