Shenzhen CTNT Zhongwei Inspection (CTNT) is an authoritative third‑party testing organization specializing in laser product testing and certification, holding multiple accreditations including CNAS, IAS, and CMA. We are committed to providing professional, high‑precision, traceable laser power testing services for laser equipment manufacturers, research institutions, and import/export enterprises worldwide, helping customers accurately master core product performance and successfully meet domestic and international market access requirements.

I. What is Laser Power?

Laser power refers to the amount of energy output by a laser per unit time, usually expressed in watts (W). It is one of the most basic and important performance indicators measuring a laser‘s working capability, directly determining the processing ability, efficiency, and effectiveness of laser equipment in practical applications. For continuous wave (CW) lasers, laser power is represented as a stable output value; for pulsed lasers, average power or single‑pulse energy is commonly used.

II. Significance of Laser Power Testing

• Product Performance Verification – Laser power is a core item in factory acceptance testing. Accurate power testing verifies whether the product meets design specifications and ensures product consistency.

• Process Quality Control – In laser processing (cutting, welding, marking, etc.), even small power fluctuations directly affect processing quality. Regular power testing helps users optimize process parameters and reduce scrap rates.

• Compliance and Market Access – Domestic and international standards such as GB/T 7247.1, IEC 60825‑1, and FDA 21 CFR 1040.10 require accurate calibration and testing of laser output power. Our reports are strong evidence for certification applications and market surveillance responses.

• R&D and Fault Diagnosis – During laser R&D and after long‑term use, power testing can assess device aging and diagnose potential faults, providing data support for product iteration and maintenance.

III. Laser Power Testing Instruments

Our laser laboratory is equipped with world‑class laser power measurement systems, ensuring data accuracy and traceability:

• Laser power/energy meters – Covering an ultra‑wide range from pW to 5 kW, meeting testing needs from low‑power light sensors to high‑power industrial lasers.

• Pyroelectric and photodiode probes – Optimal probe selection for different wavelengths (UV, visible, IR) and operating modes (pulse/CW).

• High‑speed data acquisition system – Real‑time recording of power fluctuations and pulse waveforms, supporting simultaneous testing of pulse width, repetition frequency, etc.

• Standard light source and calibration device – Regularly traced to national metrology institutes, ensuring measurement error within ±3%.

IV. Laser Power Testing Process

We follow standardized testing procedures to ensure reliable results. The specific process is as follows:

Step 1: Requirement communication – Customer submits product specifications and testing purpose (e.g., R&D verification, export certification, factory acceptance). Our engineers initially determine laser type (CW/pulse), wavelength range, and estimated power.

Step 2: Solution development – Based on the provided information, engineers determine the appropriate test plan, including probe selection (pyroelectric or photodiode), need for attenuators, number of measurement points, and environmental conditions.

Step 3: Sample receipt and confirmation – Customer mails or delivers the sample to our laboratory. Laboratory personnel confirm appearance and functionality, and register the sample for testing scheduling.

Step 4: Environmental preparation and equipment calibration – In a constant‑temperature, constant‑humidity, dust‑free darkroom environment, the laser power meter is warmed up to a stable state, and zero calibration and range verification are performed using a standard light source to ensure error is within the allowable range.

Step 5: Formal testing – According to IEC 60825‑1 or customer‑specified standard methods, the laser output is aligned with the probe‘s sensing area. After output stabilization, multiple power readings are continuously recorded. For pulsed lasers, average power is measured and single‑pulse energy is calculated.

Step 6: Data processing and judgment – The average power and standard deviation are calculated and compared with the product nominal value or standard limits. If anomalies are found, engineers repeat the test and check for possible environmental interference or equipment issues.

Step 7: Report issuance – A detailed test report (bilingual Chinese/English) is prepared, including test environment, instrument information, raw data, conclusions, and compliance judgment. The report is stamped with CNAS/CMA seals, and both electronic (PDF) and paper versions are provided.

Step 8: After‑sales interpretation and support – After report delivery, engineers can remotely or in person interpret the report data, provide cause analysis, and offer corrective recommendations for low or unstable power.

Standard turnaround: Test report issued within 7 working days after sample receipt. Expedited service available for urgent projects.
