Objective: To design and develop a portable medical laser source verification device. Methods: The design of the device is composed of five parts: milliwatt laser power detector, watt-level laser power detector, laser energy detector, laser power / energy display and laser output terminal locking device. 3 detectors share a monitor for portability purposes. Laser output terminal locking device is used to fix the relative position of the laser terminal and the detector, in order to carry out the measurement work in the medical unit site. The test equipment for performance testing and evaluation of uncertainty. Results: One set of portable medical laser source verification device was developed and the laser powers of three detectors were measurable. The energy range was 0.1 ~ 100mW, 0.1 ~ 150W, 0.01 ~ 2.0J respectively. The measurement uncertainty at the calibration wavelength was 1.5%, 2.6% and 3.3%. Conclusion: The performance of the portable medical laser source verification device has reached the design requirements and is suitable for the verification work in the field of medical units.
