Abstract
A coolant system for a high power microwave excited plasma tube is described which comprises hydraulic fluid in a coolant system structure for flowing the fluid into heat exchange relationship with the plasma tube. Such a coolant system can operate over the temperature range of -50.degree. to 150.degree. C. and may provide excellent optical transmission from 5700 to 10000 .ANG., thus being useful for cw or pulsed solid state laser pumps.
Claims6
A coolant system for a high power microwave excited plasma tube which comprises:
