We report on femtosecond (130 femto second) laser pulse removal and modification in Copper Boron Oxide thin films (CuBO₂) deposited on silicon substrate. The samples were irradiated with 100 to 500 number of laser pulses at room temperature. Micro-size constructions on the surface of exposed CuBO₂ thin films were produced and was observed using Scanning Electron Microscope (SEM). Self-prepared shapes like wrinkles, cellular erections, group of spots and cracks are observed by SEM studies. The small particles produced at initial laser pulses agglomerate into microspheres of Copper Boron Oxide. The optical properties show the high transmission value in (CuBO₂) thin films when the number of laser pulses is increased. The optical band gap energy also decreases as compared to as deposited film up to 300 number of pulses and then increases up to 500 number of pulses. The results show that femtosecond laser irradiation considerably modifies the optical properties and surface morphology of (CuBO₂) thin films.

我们报告了飞秒（130飞秒）激光脉冲的去除和在硅基板上沉积的氧化铜硼薄膜（CuBO ₂）的改性。在室温下用100至500个激光脉冲辐照样品。产生了暴露的CuBO ₂薄膜表面上的微尺寸结构，并使用扫描电子显微镜（SEM）进行了观察。通过SEM研究可以观察到自我准备的形状，例如皱纹，细胞勃起，斑点和裂纹组。初始激光脉冲产生的小颗粒聚集成氧化硼硼微球。光学性质表明（CuBO ₂）当增加激光脉冲数时的薄膜。与沉积膜相比，光学带隙能量也降低了多达300个脉冲，然后又增加了多达500个脉冲。结果表明，飞秒激光辐照极大地改变了（CuBO ₂）薄膜的光学性能和表面形态。
