optical output; light output
Technical term used in optics, electronics, and laser contexts to refer to the power or intensity of emitted light.
The optical output of this laser is 5 milliwatts.
We developed a device to measure light output.
Compound of 光 (ひかり, 'light') and 出力 (しゅつりょく, 'output'). A straightforward technical coinage.
