摘要：
Hydrodynamic focusing has been used to control the microfluidic dye laser emission intensity. In a typical three-stream flow configuration, Rhodamine 6G dye molecules dissolved in ethanol is used as focusing medium whereas pure ethanol is used as focused working solution. In the middle of the main channel, an integrated laser cavity is used for high precision monitoring of bandwidth change of the working stream. We demonstrate that when optically pumped with a frequency doubled Nd:YAG laser at 532 nm wavelength, the device provides a laser emission at 565 nm with an output intensity strongly depending on the pressure ratio of the two solutions.
