Laser Processing

Dual-sided laser processing can tap static beam shaping and splitting

Three-dimensional (3D) beam shaping improves laser processing speed and enables new industrial laser applications.

Spin size affects the way the system behaves. At spin-1/2, fully quantum spins pair up and cancel each other out (no magnetism). Spins >1/2 create magnetic order (magnetism).

Quantum switch?
