For the purpose of this note, total mass includes all components required to operate the “laser”, e.g., “laser”, power supply, heat exchanger, but excludes external optics for beam conditioning and/or delivery. f. Non-“tunable”“lasers”, having a wavelength exceeding 1 400 nm, but not exceeding 1 555 nm and having any of the following: 1.

Technical Note : For the purpose of X.A.IV.005 “wall-plug efficiency” is defined as the ratio of “laser” output power (or “average output power”) to total electrical input power required to operate the “laser”, including the power supply/conditioning and thermal conditioning/heat exchanger.
