By: Ingrid Hauer North American Hoganas New investments into laser cladding as well as wear and corrosion testing equipment have lead to the expanded use of stainless steels. Latest developments show these lower cost alloys are able to yield comparable physical properties to many of the traditional Ni-based and Co-based alloys commonly used today.

Newport Announces Terahertz Pulse Generation Kit
Newport Corporation introduces the new terahertz (THz) pulse generation kit using a sub-35-fs Ti:sapphire amplifier system. The kit can be easily integrated with a Ti:sapphire amplifier to generate terahertz pulses which can be further used for linear, nonlinear, and time-resolved spectroscopy applications.
Coherent Introduces Higher Power CEP Ultrafast Laser Amplifier
A new Carrier-Envelope Phase (CEP) stabilized, Titanium:Sapphire regenerative amplifier-based laser from Coherent, Inc. (Santa Clara, CA) now offers much higher power than any previously available system of this type. Specifically, the Legend Elite Duo CEP delivers up to 10 Watts of power, as well as higher repetition rates (up to 10 kHz), yet it does not […]
Workshop »Lasers in Silicon Photovoltaics« on May 25, 2011 in Munich
Supplying the world with electricity from renewable sources is one of the greatest challenges of the 21st century. A decisive aspect is the effort to considerably reduce the costs of generating electricity from photovoltaics and to increase cell efficiencies. But it is still a long way to make this product competitive with conventionally generated electricity, […]
Atomistic Structure and Dynamic Evolution of Shock Waves in Laser-material Interaction
By: Xinwei Wang Department of Mechanical Engineering, Iowa State University This work reports on the pioneering molecular dynamics (MD) modeling of shock waves in laser-material processing. For pulsed laser-assisted material processing with an ambient gas, the fast melting, vaporization, and phase explosion of the target is a very complicated process and will form a strong […]
