We demonstrated all polarization-maintaining (PM) Er fiber frequency combs with record-low noise by using two fast actuators, a graphene-based EOM and a bulk EOM.
We demonstrate an all polarization-maintaining Er fiber frequency comb with a record low phase noise for the locked carrier envelope offset frequency of 0.18 rad.
We demonstrate a mid-infrared source tunable from 6.7–12.7 μm via difference frequency generation in orientation-patterned GaAs, with 1.3 mW average output power. The input pulses are generated from a femtosecond Tm-doped-fiber laser system.
We demonstrate a coherent 2-μm Tm fiber laser frequency comb with a self-referenced carrier envelope offset frequency by performing octave-spanning supercontinuum generation in a periodically poled LiNbO3 waveguide.
