【Abstract】 Rhodamine 640 with rigid structure has been synthesized and its spectral and lasing behaviour measured. The absorption maximum is at 568nm and the fluorescence maximum at 620 nm.It can be pumped by a variety of light sources. It is found that Rho 640 lasing at 606 nm has low threshold and high efficiency.更多还原
