High intensity lasers usually based on OPCPA technology [1] require stable and precisely controlled repetition rate of the oscillator. Common method of repetition rate control is based on movable mirrors mounted on piezoelectric stages in free space [2]. This method has some disadvantages such as sensitivity to changes of ambient conditions and requirement for high voltage driving of piezo actuators. Different approach of fiber laser repetition rate control, which helps to overcome these shortcomings, is based on refractive index modification [3] instead of geometrical oscillator length change.
