利用Nd：GdCa_4 O（BO_3）_3（Nd：GdCOB）晶体对1061和1091 nm两个红外激光基波进行自和频，获得了紧凑、高效的538 nm绿色激光输出。在二极管泵浦功率为18.2 W时，在538 nm的绿色光谱范围内获得了1.73 W的最大输出功率，光-光转换效率为9.5%，30 min内输出功率稳定性优于3%.据我们所知，这是第一次在二极管泵浦Nd：GdCOB激光器中进行自和频的研究。
A compact and efficient green laser light at 538 nm produced by self-sum-frequency-mixing of both fundamental infrared laser waves (1061 and 1091 nm) in Nd:GdCa4O(BO3)3 (Nd:GdCOB) crystal is demonstrated. With 18.2 W of diode pump power, a maximum output power of 1.73 W in the green spectral range at 538 nm has been achieved, corresponding to an optical-to-optical conversion efficiency of 9.5%; the output power stability over 30 min is better than 3%. To the best of our knowledge, this is first work on self-sum-frequency-mixing of a diode pumped Nd:GdCOB laser.
