Femtosecond lasers can be used to create self-organized micro/nanostructures on the surface of most materials. However, on copper, these structures require significantly higher laser fluence when compared to other metals. We report a method to create self-organized structures on copper by clamping a foil of stainless steel on the copper surface pri...
Improving the heat transfer characteristics of materials can be accomplished by increasing the surface area. This surface roughening can be accomplished efficiently and directly using pulsed-laser processing. Here, laser processing of copper using a picosecond laser pulse technique produced mound-like structures, with surface morphologies and subsu...
It is very challenging to achieve near perfect absorption or emission that is both broadband and omnidirectional while utilizing a scalable fabrication process. Femtosecond laser surface processing is an emerging low-cost and large-scale manufacturing technique used to directly and permanently modify the surface properties of a material. The versat...
A comparison is made between the self-organized surface features that form on copper using femtosecond versus picosecond laser pulses. Modification of material surfaces (like metals and dielectrics) have shown to affect the properties for applications including enhancing heat transfer and producing anti-corrosive or antibacterial surfaces. Femtosec...

A TiNxOy (TiNO) material system has been synthesized in thin film form for the first time using a pulsed laser deposition process. X-ray diffraction and X-ray photoelectron spectroscopy measurements have been carried out to show partial oxidation of TiN to TiNO. The current (I)-voltage (V) characteristics recorded from TiNO films sandwiched between...
Pool boiling heat transfer with the use of femtosecond laser surface processing (FLSP) on copper surfaces has been studied. FLSP creates a self-organized micro/nanostructured surface. In the previous pool boiling heat transfer studies with stainless steel FLSP surfaces, enhancements in critical heat flux (CHF) and heat transfer coefficients (HTCs)...
