The time delay between the pump and probe pulses in attosecond time-resolved experiments, such as streaking, is commonly introduced by splitting recombining two an interferometer. This technique suffers from instability optical path lengths of arms due to mechanical vibration elements fluctuating environmental conditions. We present a with which unconventional interferometer suppressed while at same controlled within 20 RMS using feedback loop. Using this scheme, streaked spectrogram pulse was measured.
