2. Optical power meter - Wikipedia

   en.wikipedia.org/wiki/Optical_power_meter

   An optical power meter (OPM) is a device used to measure the power in an optical signal. The term usually refers to a device for testing average power in fiber optic systems. Other general purpose light power measuring devices are usually called radiometers , photometers , laser power meters (can be photodiode sensors or thermopile laser ...

4. Thermopile laser sensor - Wikipedia

   en.wikipedia.org/wiki/Thermopile_laser_sensor

   The sensitivity S [V/W] is the ratio of voltage U [V] generated due to the incident laser power P [W] on the sensor. The voltage generated depends on the Seebeck coefficient of the thermoelectric material; hence it is a material specific constant. [9] The incident power can be calculated by measuring the sensor voltage and using the formula:

5. Tokamak Fusion Test Reactor - Wikipedia

   en.wikipedia.org/wiki/Tokamak_Fusion_Test_Reactor

   The Tokamak Fusion Test Reactor (TFTR) was an experimental tokamak built at Princeton Plasma Physics Laboratory (PPPL) circa 1980 and entering service in 1982. TFTR was designed with the explicit goal of reaching scientific breakeven, the point where the heat being released from the fusion reactions in the plasma is equal or greater than the heating being supplied to the plasma by external ...

9. Power-to-weight ratio - Wikipedia

   en.wikipedia.org/wiki/Power-to-weight_ratio

   The useful power of an engine with shaft power output can be calculated using a dynamometer to measure torque and rotational speed, with maximum power reached when torque multiplied by rotational speed is a maximum. For jet engines the useful power is equal to the flight speed of the aircraft multiplied by the force, known as net thrust ...
