Due to the excellent light transmission, heat resistance, corrosion resistance, high mechanical strength, and other characteristics, transparent materials have been widely used in emerging industries such as aviation, aerospace, microelectronics, and interconnected communication, etc. Compared with the traditional mechanical processing and chemical processing of transparent materials, laser processing with such features as the high peak power, high energy density, and non-contact processing, has obvious advantages in the processing efficiency and accuracy. In this review, some frontier research progresses of laser processing of transparent materials are introduced in detail, including the basic mechanism of laser-material interaction and new laser processing technologies. Among them, some new laser processing technologies have analyzed and summarized in this paper with three new laser processing technologies: 1) Hybrid Laser-Based Processing of Transparent Materials; 2) Transparent Material Processing Based on Spatial Beam Shaping; 3) Transparent Material Processing Based on Temporal Beam Shaping. Finally, the future development prospects of processing transparent materials by lasers have been summarized and prospected in the presentation.
