Broadband Spectral Amplitude Control in High-Order Harmonic Generation
A technique for broadband spectral amplitude control of light pulses produced in high-order harmonic generation (HHG) is presented. It has been shown elsewhere that broadband spectral phase control in HHG is achievable using a computerized feedback loop scheme by coherently adding a filtered region of the HHG emission to the intense IR driving pulse with optimal attenuation and time delay param...
متن کاملHigh-spectral-resolution coherent anti-Stokes Raman scattering with interferometrically detected broadband chirped pulses.
To achieve high-spectral-resolution multiplex coherent anti-Stokes Raman scattering (CARS), one typically uses a narrowband pump pulse and a broadband Stokes pulse. This is to ensure a correspondence between anti-Stokes and vibrational frequencies. We obtain high-resolution CARS spectra of isopropanol, using a broadband chirped pump pulse and a broadband Stokes pulse, by detecting the anti-Stok...
متن کاملAttosecond Pulses through High Harmonic Generation
“To fill a vacancy in a lower-lying atomic shell, an orbiting electron has to shed energy. If it follows the Auger process, the shell-hopping electron transfers its excess energy to a neighboring electron in the same shell. Left behind with too much energy, the neighbor quits the atom. The eviction takes a few tens to a few thousands of attoseconds (10^-18s)—at least that’s what the energy spec...
متن کاملQuantum-noise measurements in high-efficiency single-pass second-harmonic generation with femtosecond pulses.
The quantum-noise properties of single-pass second-harmonic blue-light generation with femtosecond pulses have been measured. A conversion efficiency of as much as 63.5% of second-harmonic generation at 428.8 nm was observed in a KNbO(3) crystal with femtosecond (130-fs) pulses with wavelengths centered at 857.6 nm. The quantum noise on the generated blue light was measured to be 1.0 dB (1.4 dB...
متن کاملSpectral phase correlation of coded femtosecond pulses by second-harmonic generation in thick nonlinear crystals.
We demonstrate a novel all-optical scheme for measuring the correlation of spectrally phase-coded ultrashort optical waveforms that uses second-harmonic generation (SHG) in long, periodically poled lithium niobate crystals. The SHG yield can be controlled over a range of ~30 dB, depending on the correlation of the applied phase codes. Such a spectral phase correlator has applications for ultras...
