Thin gold films grown in ultra high vacuum on mica substrates
(2003)In-situ evaporation was used to deposit thin gold films (640 A) on mica substrates held at room temperature. The samples were characterized by Auger Electron Spectroscopy (AES) and Scanning Tunneling Microscopy (STM) ... -
Tunable high-power fiber laser and its application to produce Brillouin fiber lasers
(2012-11-10)A tunable continuous wave single-longitudinal-mode fiber laser is proposed and developed. A saturable absorber, as well as, an all-fiber Fabry-Perot filter was used in the laser cavity to reduce mode-hopping. The laser ... -
Tweezing and Manipulating Nanomaterials on Tapered Optical Fiber to Develop SurfaceEnhanced Raman Spectroscopy (SERS) Substrate
(2020)A compact and cost-effective fiber-based probe was manufactured for the detection of chemicals at low concentrations using Surface-Enhanced Raman Spectroscopy (SERS). Multi-mode optical fiber was tapered with a dynamic ... -
An ytterbium-doped fiber laser at 1.1 um
(2013-02-12)A pulsed ytterbium-doped fiber laser is proposed and developed. A length of samarium-doped fiber was inserted into the laser cavity to induce passive Q-switching. The laser oscillated in the continuous wave, Q-switched ...
