Focusing a tailored laser beam through transparent glass can create a tiny spot inside the material. Researchers at Tohoku University have reported on a way to use this small spot to improve laser material processing, boosting processing resolution.Laser machining, like drilling and cutting, is vital in industries such as automotive, semiconductors, and medicine.
Scientists have identified this process as promising for laser processing. However, one drawback is that this field weakens inside the material due to light refraction at the air-material interface, limiting its use. Further examination of the radially polarized beam behavior when focused with an annular shape revealed that the longitudinal field is greatly enhanced. This enhancement occurs because of total reflection at high converging angles on the back surface between the glass and air. By using an annular-shaped radially polarized beam, Kozawa and his colleagues created a small focal spot.
"This breakthrough enables direct material processing with enhanced precision using the enhanced longitudinal electric field," adds Kozawa."It offers a simple approach to realize processing scales below 100 nm and opens new possibilities for laser nano-processing in various industries and scientific fields."Physicists propose a novel way to create photoconductive circuits, where the circuit is directly patterned onto a glass surface with femtosecond laser light.
