H01S 3/11

Mode locking; Q-switching; Other giant-pulse techniques, e.g. cavity dumping

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 > Controlling the intensity, frequency, phase, polarisation or direction of the emitted radiation, e.g. switching, gating, modulating or demodulating > Mode locking; Q-switching; Other giant-pulse techniques, e.g. cavity dumping

CPC:

Lasers, i.e. devices using stimulated emission of electromagnetic radiation in the infrared, visible or ultraviolet wave range (semiconductors lasers H01S5/00) > Controlling the intensity, frequency, phase, polarisation or direction of the emitted radiation, e.g. switching, gating, modulating or demodulating > Mode locking; Q-switching; Other giant-pulse techniques, e.g. cavity dumping

Of 3 combined children, 2 exist in both systems.

1 codes are CPC-only extensions.

IPC defines codes here since 2023.
