Abstract
Pulsed-laser deposition (PLD) of thin polyethylene glycol (PEG) films using tunable infrared and ultraviolet laser was analyzed. The films were compared by fourier transform infrared spectroscopy, electrospray ionization mass spectrometry, matrix laser desorption and ionization time-of-flight mass spectrometry. Results indicated that when IR laser was tuned to a resonant feature in the organic material, the IR PLD films retained the optical, structural and physical properties of the bulk PEG material. Ultraviolet laser deposition resulted in photochemical modification of the polymer material appearing in the films.
