摘要:

采用低成本紧凑型蓝光激光二极管泵浦,在垂直外腔面发射有机激光器(VECSOL)中实现了高功率、衍射受限的有机固体激光器运转。二极管泵浦的VECSOL在聚合物基质中使用各种染料进行了演示,导致540 nm至660 nm的激光发射。优化的泵浦脉冲宽度和输出耦合导致11%的泵浦斜率效率为DCM为基础的VECSOL。我们报告输出脉冲能量高达280 nJ,100 ns长的泵浦脉冲,导致在圆对称,衍射限制光束的峰值功率为3.5 W。

英文摘要:

High-power, diffraction-limited organic solid-state laser operation has been achieved in a vertical external cavity surface-emitting organic laser (VECSOL), pumped by a low-cost compact blue laser diode. The diode-pumped VECSOLs were demonstrated with various dyes in a polymer matrix, leading to laser emissions from 540 nm to 660 nm. Optimization of both the pump pulse duration and output coupling leads to a pump slope efficiency of 11% for a DCM based VECSOLs. We report output pulse energy up to 280 nJ with 100 ns long pump pulses, leading to a peak power of 3.5 W in a circularly symmetric, diffraction-limited beam.
