TLDR
In this article, a utility model was made into a laser power meter for measuring the grade of mill watt to grade of scores of watts, which can also be used for supervising the fast change of power.Abstract:
The utility model relates to a novel laser power meter responded to all wavelengths Graphite emulsion is coated on an absorption surface facing incident light on an anode aluminum oxide sheet The back side of a light surface is plated with fifteen pairs of thermoelements by a vacuum evaporation plating method and is connected with an amplifying circuit The utility model can be made into a laser power meter for measuring the grade of mill watt to the grade of scores of watts The power response time of the power meter is less than 1s, and the sensitivity is above 18 mv/w, so the power meter can be used for measuring the laser power from ultraviolet to an infrared spectrum region and can also be used for supervising the fast change of powerread more
