High-sensitivity, simple frequency-resolved-optical-gating device
Travis Jones, Peter Šušnjar, Rok Petkovšek, Rick Trebino
Izvirni znanstveni članek
Oznake: ultrafast optics;ultrafast measurements;frequency-resolved optical gating;GRENOUILLE;
We introduce a practical self-referenced device for the complete temporal intensity-and-phase measurement of fewfemtojoule-level fs and ps pulses based on the simple version of frequency-resolved-optical gating, called GRENOUILLE. We replace the usual crossed-beam line-focus geometry with a pointfoc ...

Crystal-configuration considerations for higher-sensitivity picosecond-pulse SHG FROG
Peter Šušnjar, Travis Jones, Rick Trebino, Rok Petkovšek
Izvirni znanstveni članek
Oznake: nelinearna optika;ultrakratki laserski pulzi;FROG;karakterizacija ultrakratkih laserskih pulzov;nonlinear optics;ultrashort pulse;ultrashort pulse characterization;
We experimentally compare a thick BIBO crystal, a walk-off compensating configuration of thin BBO crystals, and a thin PPLN crystal for the use as a nonlinear medium in SHG FROG, aiming for increased sensitivity required for complete pulse characterization of low-energy (below pJ) pulses a few picos ...
