With low-timing jitter, passively mode-locked fiber lasers are very attractive seed sources for few-cycle-pulse OPCPA systems [1][2] where external synchronisation is always necessary. For precise synchronization of picosecond laser system, the timin

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

Semiconductor saturable absorber mirror (SESAM) is the key component for many passively mode-locked ultrafast laser sources. Particular set of nonlinear parameters is required to achieve self-starting mode-locking or avoid undesirable q-switch mode-l
