A laser power meter is a specialized instrument used to accurately measure the output power of laser beams. It is an essential tool in laser manufacturing, medical device maintenance, research laboratories, and field service applications where verifying laser performance is critical .
Laser power meters operate primarily on two principles:
Thermal (Thermopile) Sensors: These absorb laser energy as heat and measure the resulting temperature rise. They are robust, handle high powers (watts to kilowatts), and work across a wide wavelength range but respond relatively slowly .
Photodiode Sensors: These convert light directly into electrical current. They are highly sensitive (measuring microwatts to milliwatts), respond quickly, but are wavelength-dependent and less robust at high powers .
