Paper Abstract

We demonstrate broadband (THz) cw operation of a modeless external-cavity quantum-dot semiconductor diode laser. The laser cavity design is based on a frequency-shifted-feedback laser design using an intracavity acoustooptic frequency shifter. The rms intensity fluctuations are < 0.5% and the coherence time is 1 μs. The spectral optical power density is (see manuscript) 0.2 μW/MHz.
