New ultrashort pulsewidth measurement technology based on interference jitter and FPGA platform
文献摘要：
Conventional ultrashort pulsewidth measurement technology is autocorrelation based on second-harmonic generation;however,nonlinear crystals and bulky components are required,which usually leads to the limited wavelength range and the difficult adjustment with free-space light alignment.Here,we proposed a compact all-fiber pulsewidth measure-ment technology based on the interference jitter[IJ]and field-programmable gate array[FPGA]platform,without requiring a nonlinear optical device[e.g.,nonlinear crystal/detector].Such a technology shows a wide measurement waveband from 1 to 2.15 μm at least,a pulsewidth range from femtoseconds to 100 ps,and a small relative error of 0.15％-3.8％.In particular,a minimum pulse energy of 219 fJ is experimentally detected with an average-power-peak-power product of 1.065×10-6 W2.The IJ-FPGA technology may offer a new route for miniaturized,user-friendly,and broadband pulsewidth measurement.
