Characterization of structural irregularities in highly birefringent photonic crystal fiber based on polarization coupling by torsional acoustic wave
Form birefringence Fiber optics Photonic crystal fibers Acousto-optical devices
2015/6/10
We propose and demonstrate a novel method to characterize the variation of the birefringence induced by structural irregularities in highly birefringent photonic crystal fiber with high accuracy based...
Acoustic mapping of the back-scattering interferometer signal in a CO2 laser
CO2 laser self-mixing optical feedback back-scattering interferometer photoacoustics
2011/5/9
It is shown that a microphone placed in the laser plasma can be used for detection and observation
of the optical phenomenon such as an optical feedback in a continuous wave regime of the laser
oper...
Stabilized detection scheme of surface acoustic waves by Michelson interferometer
surface acoustic wave Michelson interferometer noncontact detection
2011/5/9
A new detection scheme of surface acoustic waves by Michelson interferometer has been proposed.
A substantial advantage of this scheme lies in its being stabilized against vibration and independent

Real-Time Monitoring of the Surface Modification of Root Dentin Using MIR-FEL-Induced Acoustic Waves
Real-time monitoring Photoacoustic spectroscopy Root surface caries
2009/6/10
For a non-invasive laser treatment, a real-time and non-contact monitoring technique is needed. We have investigated the extent of the surface modification of root dentin using photoacoustic spectrosc...
Acoustic processes in RF excited CO2 laser plasma in pulse regime
CO2 laser molecular laser gas laser pulse operation thermodynamic phenomena
2011/5/6
Acoustic response to the CO2 laser pulse generation in the arrangement of the slab-waveguide
structure is considered. The velocity of an acoustic wave in the carbon dioxide laser gas
medium is calcu...
