We demonstrate a simplified method for dissipative generation of an entangled state of two trapped-ion qubits. Our implementation produces its target state faster and with higher fidelity than previous demonstrations of dissipative entanglement generation and eliminates the need for auxiliary ions. The entangled singlet state is generated in ~7 ms with a fidelity of
0.949(4). The dominant source of infidelity is photon scattering. We discuss this error source and strategies for its mitigation.
