Our research has identified a couple of near-infrared (NIR) heptamethine indocyanine dyes exhibiting preferential tumor accumulation property for in vivo imaging. On the basis of our foregoing work, we describe here a preliminary structure-activity relati
We demonstrate a passively Q-switched Tm-doped fiber laser with carbon nantubes (CNTs), yielding a maximum output average power of around 82 mW and the corresponding pulse energy of 1.2 \mu J. The laser operates at ~1.985 \mu m with repetition rates ran
