进行了LD抽运声光调QNd：YAG激光器用于轧辊毛化的研制和毛化实验情况的研究。在毛化点阵密度为4mm×4mm的要求下，用该激光毛化装置对铬基轧辊毛化，实现了2．8kHz的频率条件下，粗糙度在6μm范围内可调，5．6kHz的频率条件下，粗糙度在4．5μm范围内可调的优良毛化性能。实现了粗糙度大范围可调、高效率、长寿命和低运行成本的LD抽运Nd：YAG激光毛化装置的成功研制。

英文摘要：

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 ram, the chromium rolls are textured using this laser texturing device. The result realizes excellent performance that the roughness is adjustable within the scope of 6μm 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.
