Laser ablation system, and method of decontaminating surfaces (US5780806)
Inventors: Russell L. Ferguson, Martin C. Edelson, Ho-ming Pang. Issued July 25, 1995 in United States
A laser ablation system comprising a laser head providing a laser output; a flexible fiber optic cable optically coupled to the laser output and transmitting laser light; an output optics assembly including a nozzle through which laser light passes; an exhaust tube in communication with the nozzle; and a blower generating a vacuum on the exhaust tube. A method of decontaminating a surface comprising the following steps: providing an acousto-optic, Q-switched Nd:YAG laser light ablation system having a fiber optically coupled output optics assembly; and operating the laser light ablation system to produce an irradiance greater than 1×107 W/cm2, and a pulse width between 80 and 170 ns.
