AI Article Synopsis
- The study introduces a new method for creating ultrashort infrared pulses that are stable in their carrier-envelope phase, operating at a frequency of 100 kHz.
- The pulses can be adjusted in wavelength from 1.6 to 2.0 µm, with durations ranging from 8.2 to 12.8 femtoseconds, allowing for advanced precision in various applications.
- The researchers also demonstrate this technology by examining the strong nonlinearity of multiphoton photoemission using a tiny metal tip.
Article Abstract
We present a simple and efficient concept for the generation of ultrashort infrared pulses with passively stabilized carrier-envelope phase at 100 kHz repetition rate. The central wavelength is tunable between 1.6 and 2.0 µm with pulse durations between 8.2 and 12.8 fs, corresponding to a sub-two-cycle duration over the whole tuning range. Pulse energies of up to 145 nJ are achieved. As a first application we measure the high nonlinearity of multiphoton photoemission from a nanoscale metal tip.
