Timing jitter in synchronized time-lens source for coherent Raman scattering imaging

Area of Science:

• Optics and Photonics
• Biomedical Imaging
• Laser Physics

Background:

• Synchronized time-lens sources enable video-rate coherent Raman scattering (CRS) imaging.
• Timing jitter between the time-lens source and mode-locked laser is critical for synchronization performance.
• Theoretical investigation of timing jitter in these systems is lacking.

Purpose of the Study:

• To numerically simulate timing jitter in a synchronized time-lens system.
• To analyze the impact of optical delay on timing jitter.
• To identify methods for reducing timing jitter.

Main Methods:

• Numerical simulation of a synchronized time-lens system.
• Parameter selection based on experimental setups.
• Analysis of timing jitter as a function of optical delay.

Main Results:

• Timing jitter is primarily influenced by the intrinsic jitter of the mode-locked laser due to optical delay.
• Simulated timing jitter closely matches experimental observations.
• Matching optical delays between components can minimize timing jitter.

Conclusions:

• Numerical simulations provide theoretical insight into timing jitter in synchronized time-lens systems.
• Optical delay is a key factor affecting timing jitter.
• Optimizing optical delay matching is essential for improving synchronization and CRS imaging performance.
