Sub-diffraction-limit fabrication of sapphire by femtosecond laser direct writing

Abstract: Sapphire has shown broad application prospects in military and medical fields, due to its high hardness, excellent corrosion resistance and high transmission in the infrared band. However, these characteristics have also brought about lots of difficulties in machining or chemical etching the material. Femtosecond laser processing with excellent characteristics including small heat-affected zones and high processing resolution ratio, has become an emerging field. Therefore, it has important application prospect… Show more

“…Femtosecond laser ablation has important applications in many scientific and engineering fields, such as nanoand micro-machining, [1][2][3][4][5][6][7][8] surface modification, [9][10][11][12] and nanoparticle generation. [13][14][15] Many theories have been proposed to explain the physical mechanisms of femtosecond laser ablation, including phase explosion, [16] critical point phase separation, [17] Coulomb explosion, [18] fragmentation, [19] and thermoelastic waves.…”
