Laser Power/Energy Meters

What Is a Laser Power or Energy Meter

A laser power meter measures the average optical power emitted by a laser source, typically expressed in watts or milliwatts. A laser energy meter measures the energy per pulse of a pulsed laser, typically expressed in joules or microjoules.

Both instruments rely on calibrated optical sensors that convert incident laser radiation into an electrical signal proportional to the optical input. The measurement accuracy depends on sensor type, wavelength calibration, response time, and thermal stability.

Sensor Technologies Used in Laser Measurement

Laser power and energy meters use different sensor technologies depending on wavelength range, power level, and temporal characteristics of the laser source.

Thermal Sensors

Thermal sensors measure laser power or energy by absorbing optical radiation and converting it into heat. These sensors are well suited for high-power lasers, broadband wavelength coverage, and applications where absolute accuracy is critical.

Thermal sensors are commonly used for continuous wave lasers, industrial laser systems, and high-energy pulsed lasers.

Photodiode Sensors

Photodiode sensors convert incident photons directly into an electrical current. They offer fast response times and high sensitivity, making them ideal for low-power lasers and fast modulation measurements.

Photodiode sensors are widely used in telecommunications, fiber-optic testing, and low-power laser applications.

Pyroelectric Sensors

Pyroelectric sensors are designed for pulsed laser energy measurement. They respond to rapid temperature changes caused by laser pulses, allowing accurate energy measurement across a wide range of pulse durations.

These sensors are commonly used in research labs, laser manufacturing, and high-energy pulsed laser applications.
