Pulsed laser deposition of oxide thin films by the fifth harmonic of a Nd:Y3Al5O12 (Nd:YAG) laser

AIP Advances, 2018
We report the pulsed laser deposition (PLD) of anatase TiO2, LaAlO3, and La0.7Ca0.3MnO3 epitaxial thin films by a fifth-harmonic Nd:Y3Al5O12 (Nd:YAG) laser.

Generation of Intense and Temporally Clean Pulses—Contrast Issues of High-Brightness Excimer Systems

Applied Sciences, 2022
In high-brightness excimer systems, the direct amplification of short pulses allows temporal filters to be integral parts of the ultraviolet (UV) amplifier chain, where the only origin of the noise is the amplified spontaneous emission (ASE), generated ...
