Electrically pumped semiconductor laser with low spatial coherence and directional emission
Kyungduk Kim, Stefan Bittner, Yongquan Zeng +3
We design and fabricate an on-chip laser source that produces a directional beam with low spatial coherence. The lasing modes are based on the axial orbit in a stable cavity and ha…

Random-laser dynamics with temporally modulated pump
Stefan Bittner, Sebastian Knitter, Seng Fatt Liew +1
We present an experimental study of the effects of temporal modulation of the pump intensity on a random laser. The nanosecond pump pulses exhibit rapid intensity fluctuations whic…
