Development of Supercontinuum Laser Source for 2 μm OCT with Tm-Ho co-doped Ultrashort Pulse Fiber Laser Using Single Wall Carbon Nanotube

Highly efficient Tm-Ho co-doped ultrashort pulse fiber laser operating at 1.9 μm was developed using single wall carbon nanotube. Wideband supercontinuum at 2.0 μm was generated and high-resolution OCT imaging of human tooth was demonstrated.
