Abstract

A novel scheme for intracavity control of the carrierenvelope offset (CEO) frequency of a 100 MHz modelocked Er:Yb:glass diode-pumped solid-state laser (DPSSL) based on the modulation of the laser gain via stimulated emission of the excited Er3+ ions is demonstrated. This method allows us to bypass the ytterbium system fewkHz low-pass filter in the fCEO stabilization loop and thus to push the phase lock bandwidth up to a limit close to the relaxation oscillations frequency of the erbium system. A phase lock bandwidth above 70 kHz has been achieved with the fully stabilized laser, leading to an integrated phase noise [1 Hz-1 MHz] of 120 mrad.
