Noniterative data inversion of phase retrieval by omega oscillating filtering for optical arbitrary waveform measurement

We propose a noniterative data inversion process for the phase retrieval by omega oscillating filtering method that could measure both isolated attosecond pulses and periodic optical arbitrary waveform (OAW). The built-in phase modulation depth recovery not only prevents the need of independent calibration (a critical advantage in the extreme ultraviolet regime) but provides a self-consistency check for the data integrity. Our experiments successfully retrieved OAW with similar to 100% duty cycle in the near infrared regime. (C) 2013 Optical Society of America
