by gas discharge of a gas laser

Introduced: July 1974

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

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

Of 7 combined children, 4 exist in both systems.

3 codes are CPC-only extensions.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1990.
