Researchers at the Carnegie Institution's Geophysical Laboratory have learned to produce 10-carat, half-inch thick single-crystal diamonds at rapid growth rates (100 micrometers per hour) using a chemical vapor deposition process.

This is the first time that artificial diamonds have been created that not only show up perfectly clear right actross the visible spectrum from ultra-violet to infra-red, but are mass-producable relatively cheaply.

Most HPHT synthetic diamond is yellow and most CVD diamond is brown, limiting their optical applications. The standard growth rate of these new crystals is 100 micrometers per hour for the Carnegie process, but growth rates in excess of 300 micrometers per hour have been reached, and 1 millimeter per hour may be possible. Combined with the astonishing growth rate, and the evgen morte impressive achievement of artificial diamonds up to an inch thick via this process, the possibilities of finally being able to use the power of diamonds in optical switching are finally upon us.
