摘要:
The generation of sub-optical-cycle, carrier–envelope phase-stable light pulses is one of the frontiers of ultrafast optics.
The two key ingredients for sub-cycle pulse generation are bandwidths substantially exceeding one octave and accurate control of the spectral phase.
These requirements are very challenging to satisfy with a single laser beam, and thus intense research activity is currently devoted to the coherent synthesis of pulses generated by separate sources.
This talk will discuss recent implementations of coherent waveform synthesis from the optical parametric (chirped-pulse) amplifiers and multi-color hollow-core fiber compressor.

Dr. Fang received bachelor and doctoral degrees from Tianjin University, China and Hokkaido University, Japan, respectively.
Since 2011 he has been a research scientist in the framework of the Helmholtz Association Young Scientist Program at DESY CFEL.
His research interests include sub-cycle waveform synthesis and novel monocycle pulse generation for attosecond science and table-top X-ray source.
