Due to its relative small losses, theoretically it is supposed to get 50% of conversion effi. ciency at a pump level of 600 mW by using a BBO crystal with cutting angle of 27.030 and length of 10mm.

• 从分析其性能出发通过计算指出，使用BBO晶体获得倍频426nm蓝光(切割角度为27.；430，长度为10mm)，虽其非线性转换系数小，但由于该晶体的损耗小，在泵浦功率约为600mW时。 理论上同样可以得到50%25的倍频转换效率。
