Fused Alumina Ceramics Bars
w/ Energizing Bar
w/ Energizing Bar
(LZR) 87700-S
Here is an idea as to what Q Source was building: they started with LZR-87005-99 (below, left) and added a U shaped aluminum energizing bar with a 0.5"W x 0.1"H strip of ceramic in the center. Then they added two LZR-8700014 (table at bottom) rods leaving a 0.05" gap to the ceramic strip / aluminum energizing bar. All appears to be glued with some kind of ceramic epoxy. The bar is exposed through the top hole of the LZR-87005-99. The ceramics were likely used to dissipate the heat of the plasma; the energizing rails used to create a high voltage capacitor within the laser chamber.

Single alumina ceramics bar.
- Dimensions: 16.85"L x 2.00"W x 0.625"H

Inner hole is 0.375" in diameter and continues another 0.188" deeper to join the 0.125" slot from side 1. Neither hole passses all the way through. The holes and slot were likely used to energize the center rail of the laser housing, via a metal bar. See LZR-81000-RA or RB (below).
