Gas dynamic lasers, i.e. with expansion of the laser gas medium to supersonic flow speeds

Introduced: January 1990

Full Title

Full titles differ between systems:

IPC:

Lasers, i.e. devices using stimulated emission of electromagnetic radiation in the infrared, visible or ultraviolet wave range > Processes or apparatus for excitation, e.g. pumping > by gas discharge of a gas laser > Gas dynamic lasers, i.e. with expansion of the laser gas medium to supersonic flow speeds

CPC:

Lasers, i.e. devices using stimulated emission of electromagnetic radiation in the infrared, visible or ultraviolet wave range (semiconductors lasers H01S5/00) > Processes or apparatus for excitation, e.g. pumping > by gas discharge of a gas laser > Gas dynamic lasers, i.e. with expansion of the laser gas medium to supersonic flow speeds

No child classifications to compare. This is a leaf node in both IPC and CPC.
