A "laser thermometer" as commonly sold is just a small FoV infrared thermometer with a laser pointer strapped on top. (The exception is very advanced thermometers which use calibrated lasers and optical ranging to measure reflectivity.)

Usually these thermometers accept emissivity as a setting. They don't measure it.
