Beschreibung

An essential part of the high-energy laser system PHELIX is its front-end which allows to achieve highest contrast levels of about twelve orders of magnitude with respect to the amplified spontaneous emission. Similar to other high-contrast systems, its technology heavily relies on the exploitation of nonlinear effects, specifically ultrafast optical parametric amplification (uOPA), rendering the output highly susceptible to fluctuations of its input. By seeding the output of the uOPA into a subsequent high-gain regenerative amplifier, a total gain of approximately seven orders of magnitude is achieved. Therefore, a precise control and stabilization of the front-end amplifiers is necessary to avoid transporting these fluctuations into the PHELIX high-energy amplifiers.
Here, I report on the current measures on automated front-end stabilization and control as well as potential automation upgrades at PHELIX.
