Scientists have captured the moment a laser "comes to life"—and what they found challenges long-held beliefs. Using a special ...

We present a colliding pulse mode-locked semiconductor laser operating in the third-harmonic mode-locked state. In passive mode-locking operation, it achieved a repetition rate of 15.4 GHz and a 2.7 ...

We consider a mode-locked (ML) quantum-dot (QD) edge-emitting semiconductor laser consisting of a reverse-biased saturable absorber and a forward-biased amplifying section. To describe the dynamics of ...

Smaller, faster, and Matter-compatible, this sleek new lock is a worthy August replacement — with a few quirks.
