“…It was recently shown [35]- [38], that TCFBG used as a stretcher in a compact CPA system utilizing a chirped volume Bragg grating (CVBG) as a pulse compressor with fixed dispersion parameters can significantly simplify setting up such a system. Any dispersion mismatch introduced by different components can be compensated by finely tuning the temperature profile applied to a TCFBG.…”

“…It was recently shown that a tunable chirped fiber Bragg grating (TCFBG) can efficiently compensate nonlinear phase up to 4π [12]. As a TCFBG can also be used as a pulse stretcher in a chirped pulse amplification technique (CPA), its use for nonlinear phase compensation offers a clear advantage in terms of compactness and robustness compared to the use of spatial light modulators (SLM-s) or other pulse-shaping techniques [30][31][32][33][34][35][36].…”

Adaptive Nonlinear Phase Compensation in a Femtosecond Hybrid Laser with Varying Pulse Repetition Rate

In this manuscript, an implementation of a tunable nonlinear phase compensation method is demonstrated on a typical femtosecond hybrid laser consisting of a fiber pre-amplifier and an additional solid-state amplifier. This enables one to achieve constant laser pulse parameters over a wide range of pulse repetition rates in such a laser. As the gain in the solid-state amplifier is inversely proportional to the input power, the shortfall in the solid-state gain at higher repetition rates must be compensated for with fiber pre-amplifier to ensure constant pulse energy. This increases the accumulated nonlinear phase and consequently alters the laser pulse parameters such as pulse duration and Strehl ratio. To overcome this issue, the nonlinear phase must be compensated for, and what is more it should be compensated for to a different extent at different pulse repetition rates. This is achieved with a tunable CFBG, used also as a pulse stretcher. Using this concept, we demonstrate that constant laser pulse parameters such as pulse energy, pulse duration and Strehl ratio can be achieved in a hybrid laser regardless of the pulse repetition rate.
