ALT has the advantage of the availability of several laser wavelengths to address the varied materials used in the manufacturing of medical devices.  CO2 and YAG lasers are typically used to micromachine Stainless Steel, cobalt-chromium alloys, nickel-titanium alloys, and other metals used in applications such as vascular implants and coronary stents.  The UV wavelength of Excimer lasers are excellent for ablating organics, polymers, urethanes, resins, and parylene.  Because this laser removes materials at the micron level, controlled depth is possible.  ALT has developed new methods for removing parylene from flat substrates and cylindrical rods.
