Abstract: | The ultra-broadband phase-sensitive optical parametric amplification and de-amplification of image in a BBO nonlinear crystal
with type I phase-matching are theoretically investigated. Amplified images with a gain of 108 and a bandwidth as broad as 420 nm are realized using a 25 GW/cm
−2 peak pump-power density with 1.125 ps chirped-pulse duration. The spatial resolution after optical parametric amplification
is estimated to be q
0 =200 rad/mm (i.e., 31.8 lines/mm), which corresponds to the size of the minimum resolvable feature of the amplified image
~5 μm. |
