【摘要】 本文阐述了医用Ｎｄ：ＹＡＧ固体激光器光输出自控系统的性能。该系统能自动将光能转换成热能（温度），引入反馈环节后，激光输出稳定度由±１９．６％，±１２．８％及±１０．８％对应不同输出功率分别提高到±３．３％，±３．０％及±１．３％；时控由０．１～９．９ｓ拓宽至１～９９ｍｉｎ。在此时间内，按设定值分周期自动控制，并自动显示激光输出的时间、光能转换成热能后的温度更多还原

【Abstract】 This paper presents the performance analyses of the output control system of medical Nd:YAG laser.The system generates high temperature with the laser.After employing the feedback circle,the output stabilities are improved from ±19.6%,±12.8% and ±10.8% up to 3.3%,±3.0% and ±1.3%;the time ranges of the control system are expanded from 0.1～9.9 s to 1～99 min.The output is controlled automatically and periodicaly according to the specified time.The duration and temperature are both displayed.更多还原
