通过使用 Nd:YAG 泵浦 KTP 光学参量振荡器，演示了 1.61 μm 的人眼安全光源，电光转换效率为 2.1%，总峰值功率转换效率为 70%，能量转换效率为 47%。当采用 Nd:YLF 激光器作为泵浦源时，可以获得类似的效率，但信号波长移入 1.54 和 1.55 μm 处定义的人眼安全波段。我们还通过沿 KTP 晶体的 y 轴传播，使用 1.064 μm 泵浦演示了用于非临界相位匹配的 1.54 μm 操作。
An eye-safe source at 1.61 μm with 2.1% wall-plug efficiency is demonstrated by use of a Nd:YAG-pumped KTP optical parametric oscillator with total peak-power conversion efficiency of 70% and an energy conversion efficiency of 47%. Similar efficiencies are obtained when one employs a Nd:YLF laser as the pump source, but the signal wavelengths move into the defined eye-safe band at 1.54 and 1.55 μm. We also demonstrate 1.54-μm operation, for noncritical phase matching, with the 1.064-μm pump by propagating along the y axis of the KTP crystal.
