Short-Pulse Laser Machining
Optical, spectroscopic, and laser probing research to improve femtosecond and picosecond laser machining technology
Enterprise Sciences supported experimental research to understand and optimize short-pulse laser machining of difficult to machine ceramic and metal materials. Machining with laser pulses that are as short as one millionth of a millionth (10-12) of a second has the theoretical advantage that very clean features can be machined because almost no heat, that otherwise melts the substrate, is deposited in the very short time of the laser pulse. This project included the conception, design and fabrication of various optical, spectroscopic, and laser probing diagnostics to monitor the evolution of the machined material as a result of laser pulse shape and to gauge the impact of machining in a normal ambient air environment.
