a ruby laser to deposit the first thin films in 1965, three years after Breech and Cross studied the laser-vaporization and excitation of atoms from solid surfaces. However, the deposited films were still inferior to those obtained by other techniques such as chemical vapor deposition and ...
This chapter is mainly based on Chrisey and Hubler’s book on ”Pulsed Laser Deposition of 3 Thin Films” . 3.2 Chronological Development of PLD 1916 - Albert Einstein postulates the stimulated emission process 1960 - Theodore H. Maiman constructs the first optical maser using a rod of ruby ...
Pulsed Laser Deposition is a technology used to grow diamond-like carbon films by providing sufficient ion energy at low temperatures, resulting in coatings with high hardness, chemical inertness, low friction, and superior wear resistance.
A thermal model to describe high-power nanosecond pulsed laser ablation of yttria (Y2O3) has been developed. This model simulates ablation of material occurring primarily through vaporization and also accounts for attenuation of the incident laser beam in the evolving vapor plume. Theoretical estimates...
TiOfilm deposition by PAPLD with biased substrates is investigated into a wide range of laser fluence and oxygen pressure. It is established that plasma of the r.f. discharge excited inside PLD chamber strongly affects the films properties. TiOfilms deposited by PAPLD were found better than thos...
