Design and Development of Laser Energy Calibration System for Medical and Cosmetic Applications in Thailand

摘要

Due to an exponential growth of utilizing laser, light, and RF for medical and medical dermatology, there have beenmany issues regarding the use of those technologies. Modern devices are straightforward to use, but they are verypowerful and are capable of considerable damage when used incorrectly, especially pulse laser, with high intensity.Since there has been an increasing use of pulse laser in medical and cosmetic applications in Thailand, and the laserpulse power and energy are needed to be calibrated. National Institute of Metrology, Thailand (NIMT) has set up a laserenergy system and provide calibration service to customers. The service supports calibration of low-level laser pulse atwavelength of Nd-YAG laser at 1064 and 532 nm and at energy range 1 mJ-100 mJ. The laser energy standard wascalibrated by National Metrology Institute of Japan (NMIJ) and compared with National Metrology Institute of Germany(PTB) measurement system under scientific collaboration MOU between NIMT & PTB.
