656.5656.5 nm red narrow-linewidth single-frequency laser
656.5 nmThe 656.5 is a 656.5 nm laser source. Output power describes the optical energy delivered per second. At the sample, irradiance also depends on the beam area and losses through the optical path, so the delivered spot must be considered along with the source rating.
