在二极管泵浦的脉冲Nd：YAG激光器谐振腔外放置一个无涂层的、1 cm长的周期性极化KTP晶体，在单程结构中获得了64%的内倍频效率（2 MW/cm ~ 2）。在7.5W的泵浦光下，晶体内部获得了平均4.8W的绿色光。在0.75 MW/cm（2）的水平下，倍增效率超过50%。测得的倍频过程的热容限（FWHM）为3.3（degree）C cm，测得的温度调谐系数为0.053 nm/（degree）C。
An internal doubling efficiency of 64% at 2 MW/cm(2)was obtained in a single-pass configuration with an uncoated, 1-cm-long, bulk periodically poled KTP crystal placed outside the resonator of a pulsed, diode-pumped Nd:YAG laser. An average of 4.8W of green light was obtained from a 7.5-W pump beam inside the crystal. Doubling efficiency exceeded 50% at levels of 0.75 MW/cm(2). The measured thermal tolerance of the doubling process (FWHM) was 3.3( degrees )C cm, and the measured temperature tuning coefficient was 0.053 nm/( degrees )C .
