  The repetition rate stabilization of an optical frequency comb based on
diode-pumped solid-state laser technology is demonstrated using an intra-cavity
electro-optic modulator. The large feedback bandwidth of such modulators allows
disciplining the comb repetition rate on a cavity-stabilized continuous-wave
laser with a locking bandwidth up to 700 kHz. This surpasses what can be
achieved with any other type of actuator reported so far. An in-loop integrated
phase noise of 133 mrad has been measured and the PM-to-AM coupling of the
electro-optic modulator has been investigated as well.
