Synchronization Module

TCBOC – Two-Color Balanced Optical Cross Correlator

Lowest noise synchronization of two femtosecond lasers

  • More than 10 mV/fs sensitivity
  • Lower than 0.5 fs noise floor
  • Down to 10 fs RMS timing jitter and timing drift

Description

The fully automated TCBOC precisely detects the relative time jitter between two independent optical pulse trains with different center wavelengths (Two Color).

The TCBOC is a natural extension to Cycle’s well-known and patented (one-color) BOC and is used for sub-femtosecond fiber link stabilization over kilometer distances. Due to a balanced optical detection scheme, the TCBOC provides exceptionally high timing sensitivity, attosecond timing resolution, amplitude invariance and robustness against environmental fluctuations. The output of the TCBOC is a baseband voltage signal that is proportional to the relative time delay between the two sources. This output can in turn be used in a phase-locked loop to synchronize the two optical sources (e.g. locking a Ti:Sapphire laser to a low-noise fiber oscillator). Standard wavelengths are 800 nm, 1030 nm and/or 1550 nm.
