A Method of Drilling Non-Straight Holes Using Laser Ablation and Plasma Amplification

Summary

Researchers at Purdue University have developed a novel manufacturing technique for creating non-straight microholes called laser ablation and plasma amplification (LAPA). Its essential physical process is the interaction among a picosecond laser pulse, plasma generated by a prior nano- or picosecond laser pulse, and a microhole sidewall. LAPA promises a solution for fast, cost-effective, high-quality manufacturing of non-straight microholes with arbitrarily varying diameters. This will have a broad impact on many related areas such as fuel efficiency improvement and the reduction of toxic gas emission to the environment.
