Abstract

Time and energy sharing is an established technique in high power cw laser applications. Especially in conjunction with modern ultrafast laser systems the combination with an energy sharing system allows to take full advantage of the laser system. By including these options into a flexible fiber beam delivery the spatial freedom can be included as well to offer new and unique freedom in designing application processes for demanding and advanced processes. We will discuss the special challenges which arise when designing a time and energy sharing system for ultrafast lasers in combination with a fiber beam delivery. The requirements for precision and security are substantially higher due to the high beam quality and energy density when guiding ultrafast laser sources and require special solutions when switching securely between different beam delivery paths. The realization of a time and energy sharing system and its integration with an ultrafast laser system will be presented.
