Single-mode laser pointer optical output is the continuous visible light power emitted by a standard handheld laser pointer operating in a single spatial mode.
A little perspective
The optical output of a single-mode laser pointer is about 5 times 1 milliwatt.
Power: 1 mW; definition.
The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.
Rated continuous optical output: 5 mW; defined upper reference; range 1 mW–5 mW.
A defined 5 mW visible laser pointer output. The 0.3 J comparison is power multiplied by 60 seconds; beam class, wavelength and actual output matter.
