Abstract
The noise characteristics of high-power laser systems are becoming more and more important for a host of high-end applications that include, for example, attosecond pulse generation [1]. For these experiments, the noise level of the driving laser is very important since the HHG-process that drives the attosecond-pulse generation depends strongly on the driving laser field. Up to now, only thin-disk lasers have been systematically investigated regarding their noise characteristics [2]. In a previous work [3], we began with the examination of the transfer function of the relative intensity noise (RIN) in a high-power fiber laser system, and found out that it can be significantly attenuated due to saturation effects. This is in accordance with previous theoretical works [4]. We also found out that the noise characteristics of the fiber laser system depends on fiber design.
