Active pump-seed-pulse synchronization for OPCPA with sub-2-fs residual timing jitter: erratum

Area of Science:

• Physics
• Optical Engineering
• Femtochemistry

Background:

• Accurate measurement of timing jitter is crucial for ultrafast laser systems.
• Previous studies claimed residual RMS timing jitter below 2 fs.
• A calibration error was identified in the original data analysis.

Purpose of the Study:

• To correct and report the accurate residual RMS timing jitter between pump and seed pulses.
• To review the calibration routine and update relevant figures.
• To ensure the reliability of timing jitter measurements in stabilized laser systems.

Main Methods:

• Reevaluation of previously collected data.
• Review of the calibration routine for timing jitter measurement.
• Application of higher precision in the calibration factor extraction.

Main Results:

• The residual RMS timing jitter was corrected to 2.76 fs (sub-3 fs).
• The original measurement of below 2 fs was underestimated due to a rounding error.
• Figure 4 has been updated to reflect the corrected timing jitter values.

Conclusions:

• The corrected timing jitter of 2.76 fs is a more accurate representation of the system's performance.
• This erratum ensures the precision and validity of the reported scientific findings.
• All other experimental results presented in the original manuscript remain unaffected.
