Voltage source control for passively mode-locked semiconductor lasers — •Pascal Sauer, Dominik Auth, Christoph Weber, and Stefan Breuer — Institute of Applied Physics, Technische Universität Darmstadt, 64289 Darmstadt, Germany

Monolithic passively mode-locked semiconductor lasers are compact versatile light sources emitting ultrashort optical pulses at high repetition rate. For pulse generation a forward biased gain section and a reverse biased saturable absorber section are implemented in one device. The negative voltage applied to the absorber does not need to be modulated, but is injected using a standard low-noise voltage source. In this contribution, we present a micro-controller based robot which can be interfaced by standard laboratory control software for automatic high-resolution mode-locking performance mapping using non-remote voltage sources.
