Use of KNbO3 Nanoneedles Based Cross-correlation Frequency-Resolved Optical Gating (XFROG) to Measure Dispersive Wave of Super-continuum Pulse Laser

摘要

Being an excellent nonlinear nanomaterial, KNbO₃ nanoneedles was used as XFROG nonlinear medium to measure the time/frequency-dependent intensity of a ~100 nm band dispersive wave, which was filtered from a super-continuum picoseconds pulse laser.
