Characterization of Ultrashort Pulse Laser by Using KNbO3 Nanoneedles Based Frequency-resolved Optical Gating (FROG)
We demonstrate a measurement of Second Harmonic Generation (SHG) FROG using potassium niobate (KN) nanoneedle clusters, instead of bulk crystal, as nonlinear medium. Using this excellent nonlinear nano-material, we characterize the pulse time/frequency-dependent intensity of a 1040nm picoseconds pulse laser. Due to the nanometer scale of this nonlinear medium, the phase matching constraints can be relaxed, and the measurement system is significantly simplified and thus more accessible for common users.
