Paper Abstract

We have developed an automatic pulsewidth tunable femtosecond Ti:sapphire laser system that can generate an output of 50fs-1ps and sub-mJ/pulse at a repetition rate of 1 kpps. The automatic pulse compressor enables on to control the pulsewidth in the range of 50fs-1ps by the use of a personal computer (PC). We describe our recent results of tailored ablation processing of advanced functional materials such as GaN, BN, and hydroxyapatite. By use of the femtosecond laser pulse tailored for a specific material, we have demonstrated precise processing without chemical composition change and heat affected zone.
