Summary form only given. Femtosecond time resolved measurement of optical phase is an important technique for characterizing ultrashort laser pulses and probing intense laser-matter interactions. For the latter, probe pulse phase shifts caused by laser induced plasma wakefields or the expansion of the critical density surface of solid density plasmas have been diagnosed by frequency domain interferometry (FDI) using multiple delay time steps between pump and probe. For such high intensity laser plasma interactions, the low repetition rate of multiterawatt class lasers and the sensitivity of such interactions to small laser fluctuations motivates the development of single shot phase diagnostic techniques. We present a new single shot ultrafast phase measurement technique based on an extension of FDI to the regime of frequency domain holography (FDH).
