Dual comb mode-locked laser: Design and stabilization

We propose a single cavity dual comb source based on a diode pumped Yb:YAG laser modelocked by quantum dot semiconductor absorber mirror. Its output consists of two orthogonally polarized pulse trains with different repetition rate. We use two phase locked loops to simultaneously stabilize both dual comb repetition rates to an external microwave reference using an electrooptical KTP crystal and a piezoelectric transducer.
