Experimental studies of titania nanotubes (TiO2) and tungsten oxide nanospheres (WO3) as devices of saturable absorption for a fiber laser in ring configuration to optical short-pulse generation are presented. A deposition technique, based on optical pressure radiation generated from a coherent source at 1550 nm is used to deposit the nanostructured materials. Since this nanomaterials can be deposited directly on the optical fiber, this proposal results very interesting for applications of saturable absorbers. Experimental results, by using nanotubes TiO2and nanospheres deposited on the fiber as a saturable absorption device, show that the TiO2nanotubes exhibit better saturable absorption properties than WO3nanospheres, generating pulses with a wavelength of 1550 nm, frequency of 10 MHz, temporally width of 4.5 ps and an output power of 1 mW. © 2010 SPIE.
