Few-cycle broadband mid-IR pulse generation via optical parametric down-conversion

Abstract

"300 μJ, 3 W, few-cycle, 3 μm OPCPA based on periodically poled stoichiometric lithium tantalate crystals," Optics Letter 44(11), 2791-2794 (2019). The content of this paper is presented in Chapter 3. Author contributions: H. Liang conceived and designed the experiment. K. Liu and S. Qu made contribution to the early-phase experimental design and developed the seed of the OPCPA system. X. Zou did the OPCPA experiment with the help from W. Li, H. Liang, K. Liu and S. Qu in experimental optimizations, pulse characterization, nonlinear pulse compression and high-harmonic generation. W. Li did the CEP stability measurement.
