"Re-melt" is the restoration of laser operating power by melting "cadmium
dendrites" out of the beam path.
"Cadmium dendrites": build-up of solid debris that occur in the tube as
the cadmium travels from the reservoir to the front of the laser tube.

My colleague, Darius Daruwala, and I will give a presentation at the
users' group on the performance characteristics of the HeCd laser for the
SLA-250 series.
