TL;DR: In this article, a volume-phase hologram based diffraction grating was proposed for astronomical spectroscopy applications, which shows promise of enhanced performance over surface-relief grating technology.

TL;DR: In this article, the authors present an introduction to this technology and give the results of an evaluation of three different volume phase holographic (VPH) gratings: a 300 line mm-1 grating optimized at 1064 nm, a 1200 line mm 1 grating designed for operation at 532 nm, and a 2400 line mm 2 grating tuned for operation in 532nm.

TL;DR: A volume phase grating is an interferometric pattern within the volume of a material which, when suitably processed, becomes a modulation of the material's index of refraction.

TL;DR: Pulse stretching and compression in a high-repetition-rate chirped-pulse Ti:sapphire regenerative amplifier is demonstrated using high-efficiency holographic transmission gratings and a quantitative dispersion measurement technique is developed to characterize dispersion of the system to the third order.

TL;DR: A volume-phase optical grating, preferably supported between substrates and prisms, uses large-angle input and output light beams to provide a very high degree of dispersion and improved separation of closely spaced wavelength channels.
