High Precision and Large Range Timing Jitter Measurement and Control of Ultrashort Laser Pulses

An attosecond precision and femtosecond range timing jitter measurement and control technique is proposed. It is based on the modulation of the combined pulse induced by relative time delay of individual pulses. The core of this timing jitter detection method is the integrated technique of optical c...

Description
Summary:An attosecond precision and femtosecond range timing jitter measurement and control technique is proposed. It is based on the modulation of the combined pulse induced by relative time delay of individual pulses. The core of this timing jitter detection method is the integrated technique of optical cross correlation and electrical energy interferometry. To illustrate this technique, a proof-of-principle experiment is demonstrated based on two 237 fs pulses. The peak-to-valley timing jitter of the two pulses to be combined is less than 700 as in 1 h and the average efficiency of coherent beam combining could reach to 91.6%.
