| Abstract Scope |
Laser welding can make ceramics integral components in devices for harsh environments as well as in optoelectronic and/or electronic packages needing visible-radio frequency transparency.
We will discuss an ultrafast pulsed laser welding approach that relies on focusing light on interfaces to ensure an optical interaction volume in ceramics to stimulate nonlinear absorption processes, causing localized melting rather than ablation. We will begin by comparing laser joining of glasses and ceramics. We will then introduce various methods for controlling the absorption and scattering properties for ceramics because the key to the technique is the interplay between linear and nonlinear optical properties and laser energy–material coupling. Finally, we will discuss results of laser material interaction on various oxide ceramics. |
