Holographic interference is widely used for fabrication of sinusoidal gratings in photosensitive optical material. We present variable surface profile gratings fabricated in photosensitive hybrid sol-gel glass by use of holographic interference. It is found by experiment that different surface profiles of gratings including sinusoidal, binary, and two-peak sinusoidal can be obtained by precise control of exposure time. The experimental results are helpful for researchers fabricating gratings by holographic interference.
