Construction or shape of optical resonators or components thereof

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 > Construction or shape of optical resonators; Accommodation of active medium therein; Shape of active medium > Construction or shape of optical resonators or components thereof

CPC:

Lasers, i.e. devices using stimulated emission of electromagnetic radiation in the infrared, visible or ultraviolet wave range (semiconductors lasers H01S5/00) > Construction or shape of optical resonators; Accommodation of active medium therein; Shape of active medium > Construction or shape of optical resonators or components thereof

CPC subdivides this area 4x more granularly than IPC with 8 additional codes.

8 codes are CPC-only extensions.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1974.
