Abstract

Opto-optical loss modulation (OOM) for stabilization of the carrier-envelope offset (CEO) frequency of a femtosecond fiber laser is performed using a collinear geometry. Amplitude-modulated 1064 nm light is fiber coupled into the optical resonator of an end-pumped SESAM-modelocked all-polarization-maintaining (PM) erbium fiber femtosecond laser, where it optically modulates the loss of the SESAM resulting in CEO modulation. A noise rejection bandwidth of 140 KHz is achieved when OOM and optical gain modulation are combined in a hybrid analog/digital loop. Collinear OOM provides a simple, all-fiber, high-speed method for improving the CEO stability of SESAM mode-locked fiber lasers.
