单频激光从有机染料溶液上的单片聚二甲基硅氧烷（PDMS）弹性体芯片演示。激光腔由单模液芯/PDMS包层通道波导和相移15阶分布反馈（DFB）结构组成。将罗丹明6 G在甲醇和乙二醇混合物中的ImM溶液用作增益介质。采用6 ns 532 nm Nd：YAG激光脉冲作为泵浦光，获得了接近0.8mJ/cm（2）的阈值泵浦能量密度和高达10倍阈值的单模运转。这种微加工染料激光器为微流体和集成光学提供了一种紧凑且廉价的相干光源，覆盖近紫外到近红外光谱区域。(c)2006年美国光学学会。
Single frequency lasing from organic dye solutions on a monolithic poly(dimethylsiloxane) (PDMS) elastomer chip is demonstrated. The laser cavity consists of a single mode liquid core/PDMS cladding channel waveguide and a phase shifted 15th order distributed feedback (DFB) structure. A 1mM solution of Rhodamine 6G in a methanol and ethylene glycol mixture was used as the gain medium. Using 6 nanosecond 532nm Nd:YAG laser pulses as the pump light, we achieved threshold pump fluence of similar to 0.8mJ/cm(2) and single-mode operation at pump levels up to ten times the threshold. This microfabricated dye laser provides a compact and inexpensive coherent light source for microfluidics and integrated optics covering from near UV to near IR spectral region.
