Abstract: Technologies pertaining to a power supply that includes a nonlinear transmission line are described herein. In an embodiment, a DC power supply comprises a pulsing circuit that receives a DC input and outputs a first plurality of pulses having a first frequency to a nonlinear transmission line. The nonlinear transmission line receives the first plurality of pulses and outputs a second plurality of pulses having a second frequency that is greater than the first frequency. The second plurality of pulses is then received at an amplifier/rectifier circuit that amplifies the second pulses to increase a voltage amplitude of the pulses, and rectifies the pulses to provide a substantially constant DC output.

Abstract: Laser ablation cleaning apparatus. An optical box containing mirrors for specially directing laser light, such as repeated pulsed CO2 laser, is mounted in a hand-held cleaning head or in a custom work head. The hand-held cleaning head can be used to safely direct laser energy to a surface to be cleaned; the laser beam ablates from the surface coatings, corrosion, and the like without harming the substrate. The custom work head is removably mountable upon the iron core stack of a conventional commercial electric generator, and features an optics box carriage that is selectively movable along the axis of the stack to direct a laser beam into the slots of the stack for cleaning.
