the first source of single-cycle light

albatross is the first source of single-cycle light at the repetition rate of a laser oscillator.

Efficiently generating near- to mid-infrared waveforms over more than three octaves is a striking demonstration of its potential. Combined with ultra-low noise of field amplitude and CEP, laser pulses are generated with high waveform fidelity. This makes albatross the ideal choice for exploring infrared opto-electronics at sub-cycle timescales and for spectroscopic measurements with unprecedented time resolution and sensitivity.
