In this paper, the current status of high-power diode laser bars for pump and direct applications are proposed. The Nd:YAG with absorption lines at 808 nm and the Yb:YAG with absorption lines at 940 nm are actually most important for high power diode laser pump applications. Compared to flash lamp pumped solid state lasers, diode pumped systems have advantages in efficiency, lifetime and beam quality. Beside the current status of industrial bar products, top values from research labs in important laser characteristics are quite above the actual level. Today, for some material processing applications, the tapered laser structure seems to be most favourable, concerning beam quality and reproducible production.
