Full Title

Full titles differ between systems:

IPC:

Devices or arrangements for the control of the intensity, colour, phase, polarisation or direction of light arriving from an independent light source, e.g. switching, gating or modulating; Non-linear optics > Non-linear optics > for parametric generation or amplification of light, infrared, or ultraviolet waves

CPC:

Devices or arrangements for the control of the intensity, colour, phase, polarisation or direction of light arriving from an independent light source, e.g. switching, gating or modulating; Non-linear optics > Non-linear optics > for parametric generation or amplification of light, infrared or ultraviolet waves

Of 3 combined children, 0 exist in both systems.
