Laser action in a DNA host is presented here for thin films composed of rhodamine 6G dye
intercalated in salmon DNA (shown schematically in the Figure). Recent reports of the
semiconducting properties of DNA inspired these authors to investigate its effects in solid‐
state dye lasing. Amplified spontaneous emission with spectral line narrowing was observed
under nanosecond optical pumping.
