Abstract
We demonstrate a simple, but robust, self-starting environmentally stable passive harmonic mode-locked femtosecond Er-fiber laser with a scalable repetition rate of up to the 10th harmonic and of supermode suppression. The repetition rate of short- and long-term operation for each harmonic appears to have no pulse dropout. Furthermore, at as low as 0.8 and 2.1 mHz standard deviation, the repetition rate is achieved by using the pump-induced nonlinearity to modulate the refractive index of the gain fiber.
