AI Article Synopsis
- * We used a special tool called a third-order autocorrelator to measure pulse features under 30 picoseconds, aiming to capture the essential aspects of mode-locking.
- * Our findings show that KLM and NPE lasers struggle with performance due to nonlinear effects, staying around a contrast level of 10, while SESAM and OPO lasers achieve better performance with contrasts above 10.
Article Abstract
We have investigated the temporal intensity contrast characteristics from a broad range of mode-locked short-pulse oscillators used for seeding high-power terawatt and petawatt-class laser systems. Saturable absorber (SESAM), Kerr lens (KLM), nonlinear polarization evolution (NPE) in optical fibers and synchronously pumped optical parametric oscillator (OPO) mode-locked sources have been measured using a third-order autocorrelator with up to 10 dynamic range. We restricted the temporal characterization to features <30 ps about the laser pulse that reflect fundamental mode-locking processes. We find additional nonlinear terms and residual higher-order dispersion limits the performance of KLM and NPE sources up to the 10 contrast level, while >10 contrast was observed from the SESAM and OPO laser pulse trains.
