Abstract
We present recent progress in development of low-jitter all-normal dispersion (ANDi) Yb-doped fiber laser. We developed a timing jitter measurement scheme employing a broadband lock-in amplifier working up to 600 MHz operational frequency which allowed us to measure single side band (SSB) phase noise and long-term drift in laser repetition rate. Following the measurement, we were able to determine timing jitter of our oscillator in the most critical frequency range (10 Hz – 10 kHz) to 1.6 ps. Long-term drift has been successfully suppressed by applying a piezo motor-based active feedback in the cavity.
