An asymmetrical reflection VHG with large angular bandwidth and high diffraction efficiency was designed. The relationship between the recording angles and the diffraction efficiency was discussed at first and several combinations of the recording angles were found. The relationship between the recording angles and the angular bandwidth was furtherly analyzed， which could obtain the optimal recording setup. The experimental results showed that when the incident angle of the reference light and signal light was 10° and 59°， the angular bandwidth of the fabricated VHG could reach 24° and the diffraction efficiency 90%. However， the wavelength shift could happen. The recording angle was modified to improve wavelength shift. The method proposed could help design a VHG with large angular bandwidth and high diffraction efficiency and present great practical value.
