Is there a competition now between YAG and electron-beam welding?
The 1-kW pulsed YAG laser is offered in three versions: the 706 for welding, the 707 for cutting, and the 708 for drilling.
A good example of the breadth of what YAG lasers are now doing is provided by Lumonics Corp, Industrial Products Div, Livonia, MI.
With new muscle and fiberoptic delivery, the neodymium-doped yttrium aluminum garnet (YAG) solid-state laser is now challenging its older [CO.sub.2] gas-laser cousin in a manner, some claim, much like the way solid-state electronics displaced their gas and vacuum-tube predecessors.
An interesting Lumonics YAG application is at the Gillette Safety Razor Co, welding Sensor razor assemblies.
While admitting that the [CO.sub.2] laser is still best for cutting out large floor-panel areas, he sees the YAG's edge is its fiberoptic delivery.
Emission intensity is one of the key parameters for the application of the YAG:Ce powder.
This indicates that for, the YAG:Ce synthesis, the annealing temperature strongly affected the growth of the particle size.
From the results obtained on the YAG:Ce powder dispersion, one can note that the YAG:Ce nanoparticles formed during the LTC synthesis were completely dispersed due to the NST method, whereas by the WDT method only a small part of the nanoparticles can be separated from the microclusters.
The powder used for the NST treatment was taken from a YAG:Ce sample annealed at 1000 [degrees]C.
"103.02-2013.39." Infrastructure and equipment provided for YAG:Ce synthesis, XRD patterns, and NST treatments were made possible in the VNU project on "Nanotechnology and Application" in the period 2010-2013 supported by the Vietnamese Government.
In Figure 9, the electroluminescence spectra of a blue LED, photoluminescence spectra of YAG:Ce, and MEH-PPV polymer are presented.
