High-efficiency coupled-cavity optical frequencycomb generation

We present a high efficiency source of picosecond pulses derived from dual cavity optical frequency comb generator. This approach overcomes the limitations single generators that are restricted to efficiencies few percent. achieve with GHz repetition rates offering over hundred times higher output than design and demonstrate tuning pulse width by varying modulation depth intra-cavity electro-optic modulator. These results provide wavelength-agnostic compact footprint for development portable pulsed laser systems timing, metrology, LIDAR applications.
