Optical Transmission Measurements Of Explosive Boiling And Liftoff Of A Layer Of Micron-Scale Water Droplets From A Krf Laser-Heated Si Substrate, Sergey I. Kudryashov, Susan D. Allen Apr 2003

Optical Transmission Measurements Of Explosive Boiling And Liftoff Of A Layer Of Micron-Scale Water Droplets From A Krf Laser-Heated Si Substrate, Sergey I. Kudryashov, Susan D. Allen

Mechanical Engineering - Daytona Beach

Water plume velocities were measured in air by optical transmission as a function of laser fluence using a KrF laser for explosive boiling and liftoff of a layer of micron-scale waterdroplets from a laser-heated Si substrate of interest for laser particle removal. The thickness of the superheated water layer near the water/Si interface determines acceleration and removal of the waterdroplets from the Si substrate.
