Technical Guide

If you need our technical team for guidance on product selection or customization, please help to provide below technical information, it helps to speed up the process.

Q A Remark
1.What is your application scenario?    
2. What type of laser is measured? CW/pulse If it is continuous laser, the average power needs to be taken into consideration. For pulsed laser, both average power and peak power need to be considered simultaneously
3. What is the laser  wavelength that needs to be measured? eg:1064nm The wavelength range of the photoelectric power meter: 250-2500nm; The wavelength range of the thermoelectric power meter is 0.19-25 μ m.
4. What is the range of laser power measured? eg:100mW Hundred watts,kilowatts, ten thousand watts. Water cooling is generally required for high power
5. What resolution is required? eg:1W  
6. How to choose between thermoelectric and photoelectric power meters?   The thermoelectric power meter is based on the thermoelectric effect. When a laser is shone on the absorber of the
power meter, the temperature rises after absorbing the light energy. The temperature difference is converted into an  electrical signal through the thermoelectric element. The wavelength range of thermoelectric type can reach the
mid-infrared 25um, suitable for medium and high power measurement, up to the ten-thousand-watt level. Meanwhile, due to the time accumulation required for temperature changes, it is suitable for high-power continuous laser measurement with a high damage threshold.

The photoelectric power meter is based on the photoelectric effect. When a laser is shone on the photodetector, the photons are absorbed by the detector material, exciting electron-hole pairs to form a photocurrent. The measurable wavelength range of the photoelectric laser power meter is relatively narrow,which is determined by the material of its detector (e.g. Si:400-1100nm). It usually operates at low power, has a fast response speed, and is suitable for measuring pulsed lasers or rapid fluctuating signals. At the same time, its damage threshold is generally low, so the input optical power should be strictly controlled.
7. Comparison of power meters with different cooling methods?   Natural cooling type laser power meters are generally only suitable for measuring low-power lasers (usually < 50W). After long-term use, the performance drift of the detector may affect the measurement sensitivity.

Air-cooled power meters use fans for heat dissipation and are suitable for medium to high power measurements (typically 50W to 500W).

However, the fans generate noise during operation,making them unsuitable for environments with high noise reduction requirements. Moreover, the fans are susceptible to dust and moisture, and their heat dissipation  efficiency will decline after long-term use.

Water-cooled power meters dissipate heat through circulating water and are suitable for high-power measurements, up to the ten-thousand-watt level. They have extremely high heat dissipation efficiency and can withstand high-power lasers for a long time. However, due to the need for circulating water for heat dissipation, they are bulky and heavy, and cannot be moved easily,making them only suitable for fixed scenarios.
8. How does the damage threshold of a power meter affect its performance?   The damage threshold refers to the maximum laser power density (W/cm²)(continuous light) or energy density (J/cm²) (pulsed light) that the detector can withstand. Exceeding the threshold will cause permanent damage to the power meter and is closely related to the size of the light spot. After focusing, if the light spot becomes smaller, it may exceed the threshold.
