  • Abstract
    We present a fibre-coupled diode laser module with an optical output power of 23 W ex 35 μm (NA 0.22). The system is based on dense wavelength division multiplexing of two narrow stripe broad-area diode laser mini-bars in an external resonator. Ultra-steep dielectric edge filters are used. By measuring the optical output power, the spectrum and the degree of polarization with and without external feedback, we determine loss mechanisms of the multiplexing unit.
