Evaluation of laser ablation threshold in polymer samples using pulsed photoacoustic technique
A V Ravi Kumar G Padmaja P Radhakrishnan V P N Nampoori C P G Vallabhan
The acoustic signals generated in solids due to interaction with pulsed laser beam is used to determine the ablation threshold of bulk polymer samples of teflon (polytetrafluoroethylene) and nylon under the irradiation from a Q-switched Nd:YAG laser at 1.06
