Femtosecond autocorrelation measurements based on two-photon photoconductivity in ZnSe.
نویسندگان
چکیده
Two-photon photoconductivity in ZnSe is used to record femtosecond autocorrelation functions. This technique requires <100 muW of average power of a typical mode-locked femtosecond Ti:sapphire laser and distinguishes itself by a dynamic range over several decades and great conversion bandwidth, permitting the sensitive correlation of pulses of a few femtoseconds.

Second harmonic generation and two-photon luminescence upconversion in glasses doped with ZnSe nanocrystalline quantum dots
We report two-photon excited emission in borosilicate glasses doped with ZnSe nanocrystalline quantum dots. The emission, predominantly near the two-photon energy and detected in the direction of the excitation beam, is in the visible, and the fundamental excitation is the near-infrared output of a tunable femtosecond laser. Depending on the two-photon energy, timeand frequency-resolved measure...
متن کاملAnomalous nonlinear photoresponse in a InGaNÕGaN heterostructure
The nonlinear ~third to fourth order! as well as linear photoconductivity in a Gallium nitride/ Indium-Gallium nitride ~GaN/InGaN! heterostructure is investigated using femtosecond pulses in the infrared ~IR! and near ultraviolet ~UV!. An anomalous IR photoresponse is explained by a four level model for the GaN region including defect density fluctuations and nonlinear carrier transport phenome...
متن کاملUltrafast partial measurement of fourth-order coherence by HBT interferometry of upconversion-based autocorrelation.
We introduce, analyze, and experimentally demonstrate a compact semiconductor-based scheme for a femtosecond-scale partial fourth-order coherence g((4)) measurements. The scheme is based on a start-stop photon-counting Hanbury Brown and Twiss (HBT) interferometry of an upconversion-based Michelson-interferometer autocorrelation. The experimental realization employs second-harmonic generation in...

متن کاملExtremely nondegenerate two-photon absorption in direct-gap semiconductors [Invited].
Two-photon absorption (2PA) spectra with pairs of extremely nondegenerate photons are measured in several direct-gap semiconductors (GaAs, CdTe, ZnO, ZnS and ZnSe) using picosecond or femtosecond pulses. In ZnSe, using photons with a ratio of energies of ~12, we obtain a 270-fold enhancement of 2PA when comparing to the corresponding degenerate 2PA coefficient at the average photon energy (ηω1 ...
