We recently demonstrated the coherent synthesis of different phase-stable pulses generated via optical parametric amplifiers (OPAs) with mJ-level energy. The multi-octave spanning bandwidth covered by OPAs, jointly with an advanced phase-control scheme, allow for the synthesis of tailored non-sinusoidal optical waveforms whose duration shrinks below a single optical cycle. Adapting the so-called parametric waveform synthesis (PWS) technology to different pump lasers will allow to further scale energy and average power, making PWS the ideal tool for controlling strong-field light-matter interactions.

53-W ultrafast non-collinear near-degenerate optical parametric oscillator

ETH Zürich, Switzerland

We present a non-collinear linear-cavity optical parametric oscillator delivering 53 W around 1030 nm with a 10.2-MHz repetition-rate and sub-picosecond pulses. The system is pumped by a frequency doubled high-power SESAM-modelocked thin-disk laser.

Two ultra-broadband OPOs in the visible spectral range

Two optical parametric oscillator systems are introduced that offer ultra-broadband tunability across the visible spectral range with femtosecond pulse durations and substantial output power. Both are based on BBO in the non-collinear phase matching geometry (NOPO). The first one is pumped in the deep blue and emits directly in the visible, the second one is pumped in the green, emits in the NIR and is converted to the visible via an intracavity sum-frequency process.

CEP-stable infrared OPCPA sources

Nicolas Thiré, Raman Maksimenka, Yoann Pertot, José Villanueva, Thomas Pinoteau, Nicolas Forget


We review several optical parametric chirped-pulse (OPCPA) systems designed to achieve extreme carrier-envelope phase (CEP) stability and/or spectral tunability in the infrared. The common architecture of these OPCPAs combines a “self-seeded” difference-frequency stage with active CEP stabilization. We demonstrate the compatibility of this architecture with a set of high-power Ytterbium pump lasers based on different amplification technologies (bulk, rod-type, thin-disk, InnoSlab).

How to generate continuously tunable ultrafast optical pulses from 4–12 µm, and applications for this versatile new light source in spectroscopy and sensing

Amongst the new engineerable semiconductor nonlinear gain materials, orientation-patterned gallium phosphide (OPGaP) is unique in allowing a 1-um laser to pump an OPO that can produce light across the near- and mid-IR regions. Using OPGaP-on-GaP we have demonstrated the generation of ultrafast optical pulses from 4–13 µm, with applications in the spectroscopy of gases, aerosols and powders. Most recently, new OPGaP-on-GaAs technology has allowed us, using fan-out and multi-grating crystals, to achieve gap-free continuous tuning from 4–12 µm.
