Laser diode bars have many single emitters arranged side-by-side and spaced approximately 0.5 mm apart, on a single slab of semiconductor material measuring approximately 0.5 mm x 10 mm in size. The individual emitters are connected in parallel which keeps the required voltage low at ~2V but increases the required current to ~50 A/bar -100 A/bar.
