A tunable optofluidic microring dye laser within a tapered hollow core microstructured optical fiber was demonstrated. The fiber core was filled with a microfluidic gain medium plug and axially pumped by a nanosecond pulse laser at 532 nm. Strong radial emission and low-threshold lasing (16 nJ/pulse) were achieved. Lasing was achieved around the surface of the microfluidic plug. Laser emission was tuned by changing the liquid surface location along the tapered fiber. The possibility of developing a tunable laser within the tapered simplified hollow core microstructured optical fiber presents opportunities for developing liquid surface position sensors and biomedical analysis.
展示了一种位于锥形空心微结构光纤内的可调谐光流体微环染料激光器。光纤纤芯填充有微流体增益介质塞，并由532nm的纳秒脉冲激光器轴向泵浦。实现了强径向发射和低阈值激光发射（16 nJ/脉冲）。在微流体塞的表面周围实现了激光发射。通过改变沿锥形光纤的液体表面位置来调谐激光发射。在锥形简化空心微结构光纤内开发可调谐激光器的可能性为开发液体表面位置传感器和生物医学分析提供了机会。
