We present THz generation in a back-cooled spintronic THz emitter in reflection geometry, excited with a high-average power Yb-laser providing up to 18.5 W at 400 kHz repetition rate. This allows us to increase the THz power.

A novel multilayer elongation optical element is developed, produced, and characterized. The element elongates a mid-infrared pulse and provides a monochromatic mid-infrared waveform for electro-optic delay tracking.

We present generation of 7.5-fs pulses at 2.3 µm driven by a carrier-envelope-phase-stabilized diode-pumped Cr:ZnS oscillator. The single-cycle waveforms exhibit exceptional stability with a residual phase jitter of 8.6 mrad (0.2 Hz − 11.4 MHz).

Diode-pumped Cr:ZnS oscillators have emerged as precursors for single-cycle infrared pulse generation with excellent noise performance. Here we demonstrate a Cr:ZnS amplifier with direct diode-pumping to boost the output of an ultrafast Cr:ZnS oscill

We demonstrate ultra-rapid electro-optic sampling (EOS) of octave-spanning mid-infrared pulses centered at 9 μm, implemented by mechanically scanning a mirror with a sonotrode resonating at 19 kHz (forward and backward acquisition at 38 kHz). The in

The necessity to precisely determine the delay between ultrashort light pulses is ubiquitous in optical metrology. For pulses originating from the same source, optical-interference-based delay tracking using a monochromatic laser affords precisions o

Carrier-envelope-phase stable, multi-octave-spanning light sources enable novel types of spectroscopy techniques with unprecedented high sensitivity and dynamic range [1] , [2] . They are thus highly sought after, especially in the mid-infrared molec
