We present new photonics and electronics packages recently developed by M Squared Lasers specifically tailored for scalable neutral atom quantum computing; a high power 1064 nm system for scalable qubit number, a phase locked system for high fidelity single qubit control, and robust cavity locked systems for high fidelity Rydberg operations. We attain driven coherence times competitive with current state-of-the-art for both ground state Raman and ground-Rydberg transitions without cavity filtering, providing an excellent platform for neutral atom quantum computing. These systems are benchmarked by creating entangled Bell states across 7 atom pairs, where we measure a peak raw fidelity of F≥0.88(2) and a peak SPAM corrected of FC≥0.93(3) via a two-qubit CZ gate.
