In the last fifteen years, initiated by the needs of the laser atom cooling community, grating-stabilized diode laser systems have emerged that cover a variety of scientific and increasingly, technical applications. The paper is intended to give an overview to the non-specialist on today's grating- tunable diode laser technology and its recent extensions, focusing on the two most frequently used designs. While the Metcalf-Littman approach is designated for far mode-hop free detuning, using mostly high quality anti-reflection-coated laser diodes, the Littrow set-up offers highest output power and most rigid operation at fixed wavelengths. The key advantage of the Littrow approach is its simplicity and the usage of standard commercial laser diodes without any special treatment. Reliable single frequency operation at about a tenth of the linewidth of the free-running laser diodes, mechanical tunability and active frequency control with diode lasers in the range from 390 to 1690 nm earn these diode laser systems a strong position in many research laboratories today. Using subsequent semiconductors the light can be amplified up to 1 Watt or frequency-doubled with an efficiency of more than 30% without loss of coherence.
