Abstract
Diffraction gratings for pulse compression generally perform best at
the Littrow angle, but reflection gratings require a nonzero deviation
angle to separate the incident and diffracted beams, so they cannot be
used at the Littrow angle. In this paper, we show both theoretically
and experimentally that most practical multilayer dielectric (MLD) and
gold reflection grating designs can be used with quite substantial
beam-deviation angles—as large as even 30°—by
mounting the grating out-of-plane and choosing the optimal
polarization. The impact of polarization when mounting out-of-plane is
explained and quantified.
