Figure Captions

Fig. 1. (a) Experimental setup. (b) Measured (left) and retrieved (right) SHG-FROG traces

of the gate pulse. (c) Time-domain waveform of the retrieved gate pulse (left) and the

spectrum of the pulse after CM3 (right). Here, CM1: Edmund Optics (highly-dispersive

ultrafast mirror), GDD=−500 fs2 @ 1000–1060 nm; CM2: custom made, GDD ~ −50 fs2 @

725 nm–1325 nm, and CM3: Edmund Optics (ultra-broadband complementary chirped

mirror), GDD=−60 fs2 @ 650–1350 nm.

Fig. 2. (a) Phase-matching conditions in the LGS crystals for DFG (upper panel) and (b)

optical parametric amplification (lower panel). The phase-matching function |sinc(∆kL/2)| is

shown as functions of the phase-matching (PM) angle and the MIR wavelength.

Fig. 3. (a) MIR spectra before (upper panel) and (b) after the two-stage OPA (lower panel).

The red dots in the lower panel show the pulse energy. The inset shows the spatial beam

profile of the MIR beam at 6 m after the LGS (OPA2).

Fig. 4. (a) The time-domain waveform of the MIR pulse after the two-stage OPA. (b) The

Fourier transform of (a). (c) 2D map of 401 time-domain waveforms measured within 20

minutes (left) and the corresponding CEPs (right). (d) 2D map of 21 average time-domain

waveforms measured within 5 hours (left) and their CEPs (right).
