Abstract

The narrowing of the spectral linewidth and the increasing of the peak intensity characteristic of laser action was observed in emission spectra of dye-infused biological tissues. The fresh tissue was infused with a solution of Rhodamine 640 perchlorate in ethanol and then excited with frequency-doubled Q-switched Nd:YAG laser pulses. The sharp spectral peaks of laser action in tissues may find applications in detection of superficial disease.
