Laser milling for micro tooling

Laser milling provides a new method of producing components for the micro tool manufacturing industry. This paper considers the technical capabilities of laser milling when applied to the machining of components for micro tooling. Characteristics important for laser milling as a micro tooling manufacturing process are reviewed. These characteristics are surface finish, aspect ratio, dimensional...

Investigation of laser milling process characteristics for micro tooling applications

Laser-assisted cryosurgery of prostate: numerical study.

A new methodology for preventing freezing damage beyond pre-specified boundaries during prostate cryosurgery is proposed herein. It consists of emitting controlled laser irradiation from the urethra, across the wall and into the prostate while conventional cryoprobes freeze the unwanted prostate tissue. The purpose of this methodology is to protect the urethral wall better and confine the desir...

Experimental and Numerical Investigation of Laser Assisted PC to Polycarbonate Welding

Laser welding is a novel method for direct joining of metals and polymers, which leads to a mechanical and chemical bond between metal and polymer. In this study, feasibility of dissimilar joining between St12 and polycarbonate is studied theoretically. Then, the ND: YAG laser is implemented to join St12 and Polycarbonate. Empirical results indicate creation of a joint between St12 and polycarb...

Electron Confinement and Heating in Laser-irradiated Micro-clusters

It is shown that a two component electron distribution can emerge in a cluster under an intense laser pulse. A bulk of internal electrons adjusts adiabatically to the laser field whereas a smaller electron population at the cluster edge can undergo stochastic heating. Self-consistent equilibrium has been found and collective modes discussed for the confined electrons.
