Pure rotational stimulated Raman scattering spectra containing nine strong spectral components were generated from a approximately 11 m long hollow-core photonic crystal fiber filled with hydrogen and pumped with nanosecond pulses having energies around 100-300 nJ. Observation of both transient and steady-state scattering threshold behavior is reported. Passage from the transient to the steady state is observed with a pulse as long as 14 ns. Convenient analytical expressions for energy and power threshold are deduced for the present configuration.
从一根填充氢气、长度约为11米的空心光子晶体光纤中产生了包含九个强光谱成分的纯转动受激拉曼散射光谱，该光纤由能量约为100 - 300纳焦的纳秒脉冲泵浦。报道了对瞬态和稳态散射阈值行为的观测。对于长达14纳秒的脉冲，观测到了从瞬态到稳态的转变。针对当前配置推导了能量和功率阈值的便捷解析表达式。
