We report on lasing action from colonies of Escherichia coli bacteria that are genetically programmed to synthesize the green fluorescent protein (GFP). When embedded in a Fabry-Perot type cavity and excited by ns-pulses of blue light (465 nm), the bacteria generate green laser emission (∼520 nm). Broad illumination of pump light yields simultaneous lasing over a large area in bacterial colonies.
我们报告了大肠杆菌（Escherichia coli）菌落的激光作用，这些大肠杆菌经过基因编程合成了绿色荧光蛋白（GFP）。当它们被嵌入法布里-珀罗（Fabry-Perot）型腔中，并通过纳秒级的蓝光脉冲（465nm）激发时，细菌会产生绿色激光发射（~520nm）。宽波段的泵浦光照射会在细菌菌落中产生大面积的同时激光。
