The Gaussian beam has been widely applied with high NA objective in many fields.The emergence of optical system aberrations,which distorts the focalsphere,put on negative impacts on Gaussian beam perf
Stimulated Brillouin Scattering(SBS) is the phase-matching beams of a counter-propagating cw pump wave and a Stokes-shifted probe pulse viaan induced acoustic wave transferred from high frequency opti
Distributed optical fiber sensing based on Brillouin optical time-domain analysis that can simultaneously measure the spatial and temporal vari-ation state of the fiber stain and temperature along the
Using the spun high-birefringence fiber as the sensing fiber,a novel vibration immunity fiber-optic current sensor is proposed.The sensing fiber composesof two fibers spun in right-handed and left-han
In order to realize the uniform coating of photoresist on large area substrates,which could hardly been attained by other methods like spin coat-ing,a slotted meniscus coating applicator has been desi
Optical manipulation technology,due to its advantages of non-contact and non-invasive,has been widely used in the operation of cells and mi-cro/nano particles ranging from dozens of nanometers to seve
The fabrication and characterization of fine silicon structures with high-quality etching profile and sidewall morphology have been increasingly demandedby several fields,such as MEMS,microfluidic chi
An optical fiber temperature sensor using two fluorescent dyes based on fluorescence intensity ratiometric (FIR) method is proposed.In our experiment,Rhodamine B and Rhodamine 110,which are temperatur
Ⅲ-nitrides materials are very promising ternary alloy system that receives a lot of attentions thanks to theirs tunable bandgap that varies from near infrared to near ultraviolet regions.
GaInP2 is a technologically important energy material for high-power red-color LDs [1] and high-efficiency solar cells [2,3].Therefore,its optical properties and electronic strictures are of particula
