In this article, the picosecond parametric amplification of a polychromatic image with a wavelength bandwidth of 140 nm and a gain of 15 dB has been obtained in a type I, LBO crystal.Abstract:
The picosecond parametric amplification of a polychromatic image with a wavelength bandwidth of 140 nm and a gain of 15 dB has been obtained in a type I, LBO crystal. Thirty per 30 points were resolved. These results are in good agreement with a numerical study of the phase-matching conditions around the collinear degeneracy where phase-matching is non- critical for the signal beam in angle as well as in wavelength.read more

Parametric Amplification of Images: From Time Gating to Noiseless Amplification
Eric Lantz,Fabrice Devaux +1 more
TL;DR: In this paper, the phase conjugate idler image can be used to cancel aberrations and phase matching conditions allow the resolution to be determined and spatial frequency filtering to be performed.

High Spatially Resolved Idler Image With a Compact Noncollinear Optical Parametric Amplifier Using a CW Laser as Signal
TL;DR: In this paper, a non-collinear optical parametric amplifier based on type-II phase matching (PM) was proposed to improve the 2D space-bandwidth product (SBP) of the idler imaging by a factor of 2.8.
