Abstract
We present timing jitter measurements of a free-running and actively stabilized modelocked integrated external-cavity surface-emitting laser (MIXSEL) generating ps-pulses around 2-GHz repetition rate and over 600 mW of average output power with <0.15% rms amplitude modulation (AM) noise. The free running rms timing-jitter was 129 fs [100 Hz to 10 MHz] and 70 fs [300 Hz to 10 MHz], which is the lowest timing jitter of a free-running passively modelocked semiconductor laser to date. Actively stabilized to an electronic reference source using a piezo-actuator, an rms timing jitter of 31 fs was obtained, representing the lowest value ever measured from a passively modelocked semiconductor disk laser between 100 Hz and 100 MHz.
