“…Unlike DFG, the SC-seeded OPCPA does not limit the spectral bandwidth. A wide SC bandwidth can also be maintained with dual crystals oriented at different angles [ 35 ] to achieve high-energy few-cycle pulses. The developed OPCPA layout operating in the SWIR spectral range can become a tabletop source for excitation of secondary radiation, such as HHG [ 19 , 20 ] .…”

We present a compact and cost-effective mJ-level femtosecond laser system operating at a center wavelength of ~2.15 µm. An affordable two-stage Yb:YAG chirped pulse amplifier provides >10 mJ, ~1.2 ps pulses at 1030 nm to pump 3-stage OPCPA based on BiBO crystals and to drive the supercontinuum seed in the YAG crystal. The energy of amplified pulses in the wavelength range of 1.95 -2.4 µm reached 2.25 mJ with a pump-tosignal conversion efficiency of ~25% in the last OPCPA stage. These pulses were compressed to 38 fs in a pair of Suprasil 300 glass prisms.

“…The generation of ultra-broadband pulses for our synthesizer is achieved by broadening a 15 fs, 0.7 mJ pulse centered at 1.8 μm from an optical-parametric-chirped-pulse amplifier (OPCPA) 45 (orange line in Fig. 1a ) in an ambient-air-filled hollow core fiber (HCF) 46 .…”

The measurement and control of light field oscillations enable the study of ultrafast phenomena on sub-cycle time scales. Electro-optic sampling (EOS) is a powerful field characterization approach, in terms of both sensitivity and dynamic range, but it has not reached beyond infrared frequencies. Here, we show the synthesis of a sub-cycle infrared-visible pulse and subsequent complete electric field characterization using EOS. The sampled bandwidth spans from 700 nm to 2700 nm (428 to 110 THz). Tailored electric-field waveforms are generated with a two-channel field synthesizer in the infrared-visible range, with a full-width at half-maximum duration as short as 3.8 fs at a central wavelength of 1.7 µm (176 THz). EOS detection of the complete bandwidth of these waveforms extends it into the visible spectral range. To demonstrate the power of our approach, we use the sub-cycle transients to inject carriers in a thin quartz sample for nonlinear photoconductive field sampling with sub-femtosecond resolution.

“…The laser system used in the experiment is described in detail in ref. [34]. Briefly, 15 fs duration pulses at 1.8 µm central wavelength with 1 mJ pulse energy were obtained from a home-built optical parametric chirped pulse amplifier (OPCPA) and spectrally broadened in an air-filled hollow-core fiber, generating an ultrabroadband spectrum spanning three octaves from 300-3000 nm.…”
