by varying the potential of the electrodes (H01S5/065 takes precedence)

Introduced: January 2000

Title

Titles differ between systems:

IPC: by varying the potential of the electrodes

CPC: by varying the potential of the electrodes (H01S5/065 takes precedence)

Full Title

Full titles differ between systems:

IPC:

Semiconductor lasers > Arrangements for controlling the laser output parameters, e.g. by operating on the active medium > by varying the potential of the electrodes

CPC:

Semiconductor lasers (superluminescent diodes H10H20/00) > Arrangements for controlling the laser output parameters, e.g. by operating on the active medium > by varying the potential of the electrodes (H01S5/065 takes precedence)

CPC subdivides this area 6x more granularly than IPC with 5 additional codes.

5 codes are CPC-only extensions.

IPC defines codes here since 2000.
