Opto-Optical Modulation of an Intra-Cavity SESAM for Low-Noise CEO Stabilization of a Femtosecond Laser

Martin Hoffmann; S. Schilt; Thomas Südmeyer

We present a CEO-stabilization technique based on optical feedback to an intra-cavity SESAM with significantly improved bandwidth compared to standard pump current control, enabling a CEO-locked Er:Yb:glass laser with ten times lower residual phase noise.

A detailed experimental study on pulse formation in ultrafast VECSELs confirms that shortest pulses require slightly positive dispersion to balance saturation effects. These results are in good agreement with simulations, confirming the quasi-soliton pulse-formation theory.
