Introduced: January 2023

Title

Titles differ between systems:

IPC: Longitudinal modes

CPC: Longitudinal modes (mode suppression using a plurality of resonators H01S3/082)

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 > Mode suppression > Longitudinal modes

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 > Mode suppression > Longitudinal modes (mode suppression using a plurality of resonators H01S3/082)

Of 2 combined children, 1 exist in both systems.

1 codes are CPC-only extensions.

IPC defines codes here since 2023.
