Wavelength dependence of optical tweezer trapping forces on dye-doped polystyrene microspheres
We present an experimental and numerical study of the wavelength dependence, near resonance, of the optical tweezer trap stiffness on three different dye-doped 1 m polystyrene spheres with peak absorptions at =625, 775, and 840 nm. Experimentally, an increase in the trap stiffness of 35% on the red side of resonance was observed for the dye-doped spheres relative to polystyrene spheres without ...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولOptical Reorientation in Dye-doped Liquid Crystals
The nonlinear optical properties of liquid crystals received considerable attention in the past decades and were reviewed by various authors. Harmonic generation in liquid crystalline phases and optical reorientation of nematics are examples of nonlinearities studied in detail. The present paper deals with the latter effect, paying special attention to the influence of absorption on the process...
متن کاملMulti-wavelength laser from dye-doped cholesteric polymer films.
A multi-wavelength laser is demonstrated using a dye-doped cholesteric polymer film whose reflection bandwidth is broadened with several oscillations. Due to the abrupt change of the density of state between oscillation peak and valley, each oscillation functions as a photonic band gap for generating a laser wavelength under the excitation of a pumping laser. As a result, a multiple wavelength ...
متن کاملInvestigation of Photocatalytic Activity of Nd-Doped ZnO Nanoparticles Using Brilliant Green Dye: Synthesis and Characterization
An Nd doped ZnO (1-5%) photocatalyst was successfully synthesized via chemical co-precipitation method. The optical property, nature, and morphology of the synthesized nanoparticles were analyzed by UV-Visible, XRD, and FESEM respectively. XRD study reveals that Nd has been effectively incorporated in the ZnO lattice in the lower level dosage; however, the crystalline nature has been distor...
