Quantum-Dot-Based Saturable Absorber With p-n Junction for Mode-Locking of Solid-State Lasers

摘要

We demonstrate stable mode-locking in a Yb:KYW laser by using a quantum-dot (QD) saturable absorber structure that incorporates a p-n junction. A reduction in the output pulse duration was measured when a reverse bias was applied to the QD saturable absorber mirror.
