ABSTRACT:
Method and apparatus for laser texturing symmetrically and simultaneously both sides of a glass containing substrate, such as a magnetic disk. There are two or more acousto-optic modulators arranged in series to obtain equal laser pulses from a first beam from a laser, apparatus for capturing a first order diffracted beam from each acousto-optic modulator; monitoring the wavelength of the laser source, providing a visible indicator or diagnostic beam for each first order diffracted beam, and combining each first order diffracted beam with its respective indicator beam to form a texturing beam for texturing each side of the substrate.
