Abstract: A monolithic diode laser arrangement contains a plurality of individual emitters which are arranged adjacent to one another on a common supporting substrate and which in each case have contact windows for electrical contact which are arranged on the respective individual emitters on a front face opposite the supporting substrate. A method for producing such a diode laser arrangement and a laser device having such a diode laser arrangement are further described.

Abstract: In a high-power diode laser, facets which lie opposite one another contain in each case an amorphous layer system composed of silicon and carbon. The layer system is formed to perform the function both of a passivation layer and of the reflection-determining functional layers. This measure makes it possible to produce a high-power diode laser having a high COD threshold in conjunction with a long service life by way of a simplified method.

Abstract: An anode casing having a bright tin or bright tin alloy surface layer at least on an inside surface of the casing, preferably on the entire surface of the anode casing, and to an electrochemical cell containing the anode casing. Methods for preparing anode casings and electrochemical cells containing the anode casings are disclosed. In a preferred embodiment, the anode casings are plated at high current density utilizing a variable contact rack plating process, wherein portions of a clamp assembly of the device variably or alternately contact different portions of the anode casing so the entire surface of the anode casing is plated. The bright tin-plated surface is a high hydrogen-overvoltage metal that reduces gassing in cells using the casings.
