Optimization of Uv Laser Scribing Process for Led Sapphire Wafers
Billions of LEDs are used today in traffic control, automotive headlights, flat panel display technology, mobile devices, back lighting, projection and general illumination applications. With the dramatic growth in LEDs, manufacturers are looking for technologies to increase production yield and decrease cost. Sapphire wafer singulation into miniature dies is one of the critical steps used in b...

متن کاملLaser-assisted hair removal: comparison of long-pulsed alexandrite and long-pulsed Nd:YAG lasers, individually and in combination
Background and aim: Laser is one of the most recent techniques which has widespread use in the treatment of many skin diseases. This technique has been successfully used to remove unwanted hairs in hirsutism. The aim of this study was to evaluate and compare the efficacy and safety of long-pulsed 755 nm alexandrite and long-pulsed 1064 nm Nd: YAG lasers individually and in combination for perma...
متن کاملGas Jet–Workpiece Interactions in Laser Machining
Laser machining efficiency and quality are closely related to gas pressure, nozzle geometry, and standoff distance. Modeling studies of laser machining rarely incorporate gas effects in part because of the complex structure and turbulent nature of jet flow. In this paper, the interaction of a supersonic, turbulent axisymmetric jet with the workpiece is studied. Numerical simulations are carried...
