A high quality fixed holographic grating was recorded in a photorefractive :Fe crystal at about in a homemade temperature-controlled vacuum chamber. The recording was carried out using self-stabilization techniques with beams guided onto the crystal by polarization maintaining fibers. The diffraction efficiency of the fixed grating was when measured in the recording setup using the same recording beams. A compatible η was measured with in an auxiliary setup, and a angular Bragg selectivity at FWMH was estimated, thus demonstrating the uniformity and good quality of the fixed grating.
