Energetic ultrashort pulses with durations below one optical cycle are highly intriguing for attosecond science among other strong-field driven applications. For the generation of such sub-cycle pulses a coherent bandwidth wider than one octave is required. We recently pioneered the generation of such millijoule level sub-cycle pulses using parametric waveform synthesis (PWS). With such pulses, we achieve direct isolated attosecond pulse generation via high-harmonic generation without the need for additional gating techniques. Additionally the PWS offers to manipulate the synthesized waveform, giving precise tuning capability to shape the attosecond pulses.

Wavelength-tunable few-cycle pulses with millijoule-level pulse energies in the short-wavelength IR for ultrafast control of molecular dynamics

We present a flexible few-cycle pulsed laser source in the short-wavelength infrared spectral region. It combines a quasi-continuous center wavelength tunability over one octave (1–2 µm) with a millijoule-level output and an exceptional long-term stability (<1.2% rms over >160 h at 1750 nm center wavelength). This is realized by spectral broadening in a 3.2m stretched hollow-core fiber with adaptable focusing optics, few-cycle bulk compression and extensive characterization of the pulses. The 1 kHz repetition-rate source is utilized for soft x-ray high-order harmonic generation and subsequent strong-field transient-absorption experiments.

New platforms for generating and characterizing few-cycle laser waveforms

Michael Chini

University of Central Florida, United States of America

Attosecond science relies upon the generation, characterization, and control of intense, few-cycle laser pulses with well-controlled electric field waveforms. Generating such pulses has, for decades, relied upon state-of-the-art laser systems accessible in only a few laboratories worldwide, while characterization of their electric field waveforms has required complex pump-probe setups. In this talk, I will show that the delayed rotational nonlinearity of molecular gases can be harnessed for extreme compression and frequency conversion of industrial-grade lasers, and I will present a new technique for single-shot characterization of the generated laser waveforms.

Characterization of mid-infrared few-cycle pulses: temporal profile and CEP stability

Adrien Leblanc1,2

1LOA, CNRS, France; 2INSTN-EMT, Varennes, CA

We report on three novel tools to generate and characterize few-cycle pulses in the mid-infrared. This toolbox enables the generation of high mid-infrared fields, and the characterization of their temporal profiles and carrier-to-envelop phase stability.

Rotational Doppler effect for characterizing femtosecond laser pulses

A new variant of SPIDER (Spectral Phase Interferometry for Direct Electric field Reconstruction) method is presented. The method called DEER-SPIDER for Doppler Effect E-field Replication is based on a non-standard effect, the so-called “rotational Doppler effect”, for producing the frequency shear. It provides a spectral shearing at/near the fundamental wavelength, enabling operation of the technique in the ultraviolet spectral range. The method, evaluated under two different conditions, provide reconstructions of high reliability. Possible improvements and outlook are discussed
