Non-Thermal Ablation Lasers

Non-Thermal Ablation Lasers

Non-thermal laser ablation is a process which is rapidly growing in popularity as the cost of picosecond and femtosecond lasers are becoming more available. Traditional laser ablation methods cannot be utilized to produce high tolerance machined parts of with such small feature size, due to the heat generated in the ablation process.  As a result, it is necessary to utilized ultra-fast lasers which have an electric field density large enough to generate a Coulomb explosion.  This explosion caused by short pulse non-thermal ablation lasers can remove the material via a “cold ablation” process, therefore, preserving the integrity of the surrounding material.  In addition to the tolerancing advantage of Coulomb explosion in comparison to thermal ablation, there is the added benefit that since this is an electronic effect there is no need to take the materials absorption properties into account making this a wavelength independent process.  On this page, you will find a list of all of the non-thermal lasers we offer at RPMC, including both picosecond and femtosecond lasers.
