摘要
本工作首次在新型Nd∶Gd_(0.1)Y_(0.9)AlO_(3)(Nd∶GYAP)晶体上实现了540 nm倍频绿光激光器。Nd∶GYAP晶体产生在1μm波段的基频激光中心波长为1079.4 nm,在此基础上利用LBO晶体产生的倍频绿色激光的中心波长为539.4 nm,阈值为46 mW,最大输出功率为65 mW。这一激光系统产生的约为540 nm的绿色激光相较于传统Nd离子掺杂的晶体1064 nm激光倍频而来的532 nm绿色激光,可以有效地避开Nd^(3+)位于530 nm附近的吸收峰。因此,具有更长波长、发射峰位于约540 nm处的绿色激光器可以使激光输出更有效,并扩展绿色激光器的应用。
The 540 nm frequency-doubled green laser was first realized on a novel Nd∶Gd_(0.1)Y_(0.9)AlO_(3)(Nd∶GYAP)crystal.The fundamental-frequency wavelength that was generated by Nd∶GYAP crystal centered at 1079.4 nm,and the frequency-doubled green laser was centered at 539.4 nm with a threshold of 46 mW and a maximum output power of 65 mW.An LBO was selected as the frequency-doubling crystal.The~540 nm green laser can avoid the absorption peak of Nd^(3+)at near 530 nm.The green laser with longer wavelengths at approximately 540 nm can make the output more efficient,and expand the application of the green laser.
