Electro-Optical Synchronization System with Femtosecond Precision
Dispersion compensation devices Femtosecond phenomena
2015/6/8
A novel system for the RF synchronization is presented. It makes use of standard, commercially-available telecommunication optical components. The added timing jitter of 5 fs RMS has been measured on ...
Focusing of a femtosecond vortex light pulse through a high numerical aperture objective
Ultrafast phenomena Singular Optics Diffraction Theory
2013/7/2
We investigate the focusing properties of a femtosecond vortex light pulse focused by a high numerical aperture objective. By using the Richards-Wolf vectorial diffraction method...
Excitataion Energy Transfer Processes and Mechanisms in Photosynthetic Antenna System “Analyses by Femtosecond and Picosecond Time-Resolved Fluorescence Spectroscopy”
Excitation energy transfer Photosynthesis Antenna system
2009/6/9
Excitation energy transfer pathways and mechanisms in the antenna systems of oxygenic photosynthetic organisms were discussed from the viewpoint of methodology of analyses. Time-resolved fluorescence ...
Nano-Processing of Transparent Materials by Focussed Femtosecond Laser Pulses for the Development of Novel Bio-Microchip
Femtosecond laser Silica glass Chemical etching
2009/6/8
We report fabrication of three-dimensional (3-D) microchannels inside transparent materials. The 3-D microfabrication was achieved by two steps. First, femtosecond pulses were focussed into the transp...
Femtosecond Cascaded Second-Order Nonlinearities in Quasi-Phase-Matching Devices
Frequency conversions Cascaded second-order nonlinearities Optical solitons
2009/6/8
Cascaded processes of energy exchanges between optical beams via second-order nonlinearities lead to various phenomena, including Kerr-like nonlinear phase shifts and optical solitons. The cascading n...

Femtosecond laser Hydroxyapatite Laser ablation
2009/6/8
The micromachining of hydroxyapatite (HAp) and collagen is highly required for orthopedics and dentistry, because human bone and tooth consist mainly of HAp oriented along the collagen. We have evalua...
Single Cell Manipulation Using Femtosecond Laser Induced Shockwave
Femtosecond laser Micro processing Laser induced shockwave
2009/6/8
A shockwave induced by focusing an intense femtosecond laser on a culture medium under a microscope was applied to manipulate single bio-cell. Propagation dynamics of the shockwave was investigated by...
Three-dimensional Femtosecond Laser Integration in Glasses
Femtosecond laser microfabrication Three-dimensional integration Glass chips
2009/6/1
In the past decade, femtosecond (fs) laser microfabrication has received significant attention because of its powerful three-dimensional (3D) integrating and manufacturing capabilities. A series of mu...
Processing microstructure on film by femtosecond laser
femtosecond laser Au/Cr film process
2011/5/10
Selective laser patterning of thin films in a multilayer film is an emerging technology for fabrication of MEMS devices. A 775 nm Ti:sapphire laser (130 fs, 1 kHZ) was used to irradiate the thin film ...
Optical frequency synthesizer based on selectively injection-locked DFB lasers from a femtosecond fiber laser comb
Optical frequency synthesizer DFB lasers fiber laser comb
2015/8/4
We present an optical frequency synthesizer based on two DFB lasers that can be selectively injection-locked to a desired single mode among the femtosecond fiber laser comb components.
Grating Writing Through the Polyimide Fibre Coating with Femtosecond IR Radiation and a Phase Mask
Grating Writing Through Polyimide Fibre Coating Femtosecond IR Radiation
2015/8/4
Fibre Bragg gratings were written through the polyimide coating of commercial high NA fibres with ultrafast 800 nm radiation. Index modulations =2X10 -4 remain after 140 hours at 360°C.
