作者报告相位荧光测量使用直接调幅670-和791-nm激光二极管作为激发源。荧光寿命范围从220 ps到1.7 ns的测量使用商业相位荧光计。结果发现，当二极管上的直流电流增加时，需要更高的射频功率量来实现可比较的调制程度，并且高于一定水平的射频功率在光输出中产生失真。结果示出了在840 nm波长处发射的普通花青激光染料。
The authors report phase fluorometrlc measurements using directly amplitude-modulated 670-and 791-nm laser diodes as the excitation source. Fluorescence lifetimes ranging from 220 ps to 1.7 ns were measured using a commercial phase fluorometer. It was found that higher amounts of radio frequency power were required to achieve comparable degrees of modulation when the dc current on the diode was Increased and that rf power above a certain level created distortion In the light output. Results are shown for common cyanine laser dyes emitting at wavelengths to 840 nm.
