Demonstration of 11-ps exposure time of a framing camera using pulse-dilation technology and a magnetic lens

Abstract

A framing camera with high temporal and spatial resolution is demonstrated using pulse-dilation technology and a magnetic lens. The magnetic field of the magnetic lens is simulated using LORENTZ-3EM software, and the magnetic field distribution on-axis is similar to a Gaussian function. The temporal and spatial resolutions of the instrument are measured using light at the wavelength of 266 nm from a frequency tripled femtosecond laser. The measured exposure time of this camera is ∼11 ps, and the spatial resolution is better than 100 μm.
