Abstract

The effect of ultrashort pulse modulation on the formation of a modified zone of a transparent dielectric was investigated. The use of a femtosecond fiber laser in burst mode made it possible to control the energy that enters the processed material and thereby influence the geometry of the modification zone. In the course of the study, various types of pulses were tested—linear, sinusoidal, exponential, etc. It was noted that pulse modulation significantly affects the shape of the modified zone. Energy thresholds have been determined that lead to internal defects in the form of cracks.

猝发模式调制超短脉冲激光器对激光加工透明电介质的影响

研究了超短脉冲调制对透明电介质改性区形成的影响。在猝发模式下使用飞秒光纤激光器可以控制进入加工材料的能量，从而影响改性区的几何形状。在研究过程中，测试了各种类型的脉冲--线性、正弦、指数等。研究发现，脉冲调制对改性区的形状有很大影响。已确定的能量阈值会导致裂纹形式的内部缺陷。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
