LLNL researchers have designed and tested performance characteristics for a multichannel pyrometer that works in the NIR from 1200 to 2000 nm. A single datapoint without averaging can be acquired in 14 microseconds (sampling rate of 70,000/s). In conjunction with a diamond anvil cell, the system still works down to about 830K.

LLNL scientists have developed a new metal additive manufacturing technique that uses diode lasers in conjunction with a programmable mask to generate 2D patterns of energy at the powder surface. The method can produce entire layers in a single laser shot, rather than producing layers spot by spot as is currently done in powder bed fusion methods.
