Processes or apparatus for excitation, e.g. pumping

Introduced: September 1968

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

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

Of 6 combined children, 4 exist in both systems.

2 codes are CPC-only extensions.

IPC defines codes here since 1974.
