Abstract A study on the nanosecond laser radiation with second harmonic generation in one-dimensional ANDS samples is presented for the first time. The 71 μm wide, 8 mm long one-dimensional ANDS sample has achieved a green output power of 1.93 mW under a coupled fundamental light power of 359.26 mW. The power conversion efficiency of the microstructure is similar to 1.5 × 10−2 W−1, and the laser threshold is 125 mW (pulse energy = 6.25 μJ). In addition, power measurements of four different samples show that the conversion efficiency is influenced by samples length and cross section size.

纳秒激光辐射脉冲在一维ANDS微结构中产生二次谐波

摘要 首次对一维ANDS样品中产生二次谐波的纳秒激光辐射进行了研究。71 μm 宽、8 mm 长的一维 ANDS 样品在 359.26 mW 的耦合基本光功率下实现了 1.93 mW 的绿色输出功率。微结构的功率转换效率类似于 1.5 × 10-2 W-1，激光阈值为 125 mW（脉冲能量 = 6.25 μJ）。此外，四个不同样品的功率测量表明，转换效率受样品长度和横截面尺寸的影响。
