Abstract

For years the international laser community has been discussing what the "best" concept for high power solid state lasers might be. With the advent of high power diode lasers of lifetimes in excess of 10,000 hours at long term operational power levels around 50W per diode bar, diode pumped concepts moved into their rightful role as next generation sources. The main reason for this trend is the combination of laser efficiencies in the range of 15 to 25% at powers of several kW with the well known and increasingly applied advantage of fiber coupling. A particularly promising perspective similar to electrical networks is provided by concepts of laser power networks distributing the optical energy on demand in the production environment, especially for large scale production.
