Femtosecond laser pulse generation with a fiber taper embedded in carbon nanotube/polymer composite.
Khanh Kieu,Masud Mansuripur +1 more
TL;DR: An embedded fiber-taper saturable absorber is proposed and demonstrated based on a fiber taper embedded in a carbon nanotube/polymer composite and an all-fiber mode-locked ring laser is built.
Journal ArticleDOI
Stimulated Raman Scattering Microscopy with a Robust Fibre Laser Source
Christian W. Freudiger,Wenlong Yang,Gary R. Holtom,Nasser Peyghambarian,X. Sunney Xie,Khanh Kieu +5 more
TL;DR: To circumvent the high-frequency laser noise intrinsic to amplified fibre lasers, this work presents an optimized all-fibre laser system based on the optical synchronization of two picosecond power amplifiers and further developed a high-speed noise cancellation systembased on voltage-subtraction autobalanced detection.
Journal ArticleDOI
Sub-100 fs pulses at watt-level powers from a dissipative-soliton fiber laser.
TL;DR: A mode-locked fiber laser is reported that exploits dissipative-soliton pulse shaping along with cladding pumping for high average power and dechirped pulses at 70 MHz repetition rate.
Journal ArticleDOI
Soliton Thulium-Doped Fiber Laser With Carbon Nanotube Saturable Absorber
Khanh Kieu,Frank W. Wise +1 more
TL;DR: Stabilization of a thulium-holmium codoped fiber soliton laser with a saturable absorber based on carbon nanotubes with transform-limited 750-fs pulses with 0.5-nJ energy is reported.
Journal ArticleDOI
Biconical Fiber Taper Sensors
Khanh Kieu,Masud Mansuripur +1 more
TL;DR: In this article, the authors present several simple sensitive fiber-optics-based sensors that utilize a biconical fiber taper, such as a displacement sensor with 100nm accuracy, a temperature monitor with sensitivity DeltaT 1.42times10-5, and a refractive-index sensor capable of measuring Deltan~1.42
