Extreme ultraviolet frequency comb metrology.
The remarkable precision of frequency-comb (FC) lasers is transferred to the extreme ultraviolet (XUV, wavelengths shorter than 100 nm), a frequency region previously not accessible to these devices. A frequency comb at XUV wavelengths near 51 nm is generated by amplification and coherent up-conversion of a pair of pulses originating from a near-infrared femtosecond FC laser. The phase coherenc...
متن کاملOptical frequency comb metrology from infrared to extreme ultraviolet wavelengths
We report on frequency comb generation at 1.5 μm by injection of a CW laser in a hybridly1 mode-locked InAs/InP two-section quantum-dot laser (HMLQDL). The generated comb has > 60 modes spaced by ∼ 4.5 GHz and a -20 dBc width of> 100 GHz (23modes) at> 30 dB signal to background ratio. Comb generation was observed with the CW laser (red) detuned more than 20 nm outside the HMLQDL spectrum, spann...
متن کاملPtychographic hyperspectral spectromicroscopy with an extreme ultraviolet high harmonic comb.
We report a proof-of-principle demonstration of a new scheme of spectromicroscopy in the extreme ultraviolet (EUV) spectral range, where the spectral response of the sample at different wavelengths is imaged simultaneously. This scheme is enabled by combining ptychographic information multiplexing (PIM) with a tabletop EUV source based on high harmonic generation, where four spectrally narrow h...
متن کاملPrecision Laser Spectroscopy in the Extreme Ultraviolet
Techniques for the production of short wavelengths in the extreme ultraviolet wavelength range aredescribed, spanning low-order harmonic generation in the perturbative regime for narrow bandwidth XUV productionto the plateau-regime with the three-step collisional model for the generation of high harmonics with broadband ultrafastpulses. In addition, the intermediate regime is discus...
