摘要

报道了一种新的丝状离散线超连续谱生成方法。它基于分布式反馈染料激光作用,而不是传统的飞秒脉冲通过露天或光子分子传播。该方法技术新颖、简便、经济,具有连续谱线生成的吸引力。虽然,这项工作是通过仅用6个脉冲泵送染料溶液来产生45 nm宽的超连续光谱,由9条不同的相干线组成,但该原理可以扩展到任何所需的光谱范围,具体取决于可用的增益介质和泵送脉冲的数量。利用锁模倍皮秒Nd:YAG激光器成功地设计和运行了非白色超连续介质多波长激光源,以演示大气中的成丝现象。

Filamentation and discrete supercontinuum generation in dielectric materials
A new method of filamentary discrete lines supercontinuum generation is reported. It is based on distributed feedback dye laser action instead of the conventional propagation of femtosecond pulses through open air or photonic molecules. Novelty of the technique, ease and economy make it attractive for continual spectral lines generation. Although, this work was carried out by pumping dye solution with only six pulses to generate 45 nm wide supercontinuum, consisting of nine distinct coherent lines, but the principle may be extended to any desired spectral range, depending upon the available gain medium and number of pumping pulses. Successful design and operation of multi-wavelength laser source, an off white supercontinuum, using a mode-locked and frequency doubled picosecond Nd:YAG laser is presented to demonstrate filamentation in atmosphere.
