Development of roll texturing with LD pumped acousto-optically Q-switched Nd:YAG laser and the texturing experiments are carried out. With the request of roughening reticular density of 4 mm×4 mm, the chromium rolls are textured using this laser texturing device. The result realizes excellent performance that the roughness is adjustable within the scope of 6 μm under the frequency of 2.8 kHz and the adjustable range is 4.5 μm under the frequency of 5.6 kHz. It realizes successfully the development of LD pumped Nd:YAG laser texturing device with long adjustable roughness range, high efficiency, long life time and low operating cost.
