ULTRA STABLE COHERENT SOURCES BASED ON INJECTION LOCKED DFB FROM A FEMTOSECOND FIBER LASER COMB

− We propose ultra stable coherent laser sources based on optical injection locked single mode of the femtosecond fiber laser comb. The source is discretely tunable coherent optical sources by two DFB lasers, which are injection-locked to a respective single mode of the fiber laser comb with the frequency difference of 500 MHz, that is exactly twice of the comb repetition frequency.
