Abstract :
We have demonstrated generation of a highly accurate THz continuous wave based on a fs-pulse fiber comb. Applying ultra-narrow optical filtering based on stimulated Brillouin scattering to the fs fiber comb having a repetition rate of 100MHz enables extraction of only two optical modes of the fs fiber laser to generate a highly stable 100GHz wave.
