We experimentally compare the linewidth of the individual modes of an extended cavity
semiconductor laser when it operates mode locked and when it operates single mode. We …

We report what is to our knowledge the first observation of synchronous coherent injection
locking of an actively mode-locked extended cavity semiconductor laser to an external light …

We show that the spontaneous emission inside an injection-locked semiconductor laser
does not alter the lasing field. For injection at the free-running frequency, the linewidth is …

We have used coherent photon seeding to reduce the noise in an actively mode-locked
extended-cavity semiconductor laser. Feedback is provided by an auxiliary cavity terminated …

We present experimental results of the dynamics in a semiconductor laser operating on
several longitudinal modes subject to external feedback. Both low-frequency fluctuations …

We analyze the stability of phase-locked emission modes of a semiconductor laser subject
to both optical feedback and continuous-wave optical injection. We consider a large external …

We report a method that enables an external‐cavity semiconductor laser to be actively mode
locked at multiples of the radio frequency (rf) drive frequency. The key to this method is the …

Optical pulses with durations of a few tens of femtoseconds are used to drive applications
ranging from attoscience to metrology, but femtosecond lasers remain bulky and expensive …

We experimentally investigate the temporal evolution of the power of an external cavity
semiconductor laser in the low-frequency fluctuation regime with subnanosecond resolution …

We investigate the dynamical origin of low-frequency fluctuations (LFFs) in external cavity
semiconductor lasers by utilizing a simplified, three-dimensional model derived from the …
