IS03–Simulation of cascaded polarization-coupled systems of broad-area semiconductor lasers

Radziunas M., Montiel-Ponsoda J., Garre-Werner G., Raab V.

We present a brightness- and power-scalable polarization beam combining scheme for high-power, broad-area semiconductor lasers. To achieve the beam combining, we employ Lyot-filtered optical reinjection from an external cavity, which forces lasing of the individual diodes on interleaved frequency combs with overlapping envelopes and enables a high optical coupling efficiency. We demonstrate how repeatedly introduced […]
