A 21.4 mm long noncritically cut CdSiP2 crystal, pumped by 8 ns pulses at 1064 nm in a double-pass configuration for pump, signal, and idler, generated 523 μJ, 5.8 ns idler pulses at 6.125 μm. The average power of 52.3 mW at the repetition rate of 100 Hz is the highest ever achieved at such wavelengths with direct down conversion from the 1 μm spectral range.
一个 21.4 毫米长的非临界切割 CdSiP2 晶体,在双通配置中用 1064nm 的 8ns 脉冲泵浦,用于泵浦、信号和闲频光,在 6.125μm 处产生 523μJ、5.8ns 的闲频光脉冲。在 100Hz 的重复率下,52.3mW 的平均功率是在直接从 1μm 光谱范围下转换到如此波长时所达到的最高值。
