Abstract

GZO transparent conductive films were prepared by RF magnetron sputtering.The influence of thickness on GZO films was studied by several methods,including atomic force microscopy,XRD,Hall Effect tester and UV-Vis spectrophotometer.LEDs with GZO transparent conductive layers were also fabricated.These results show that,as the thickness increases,the crystal quality is improved and the resistivity of the film is reduced.When the thickness reached 500 nm,the lowest resistivity of 2.79 × 10-4 Ω.cm and the highest transmittance of 97.9% at 460 nm wavelength were obtained.However,the variation of film thickness has little effect on the forward voltage of LED.But it is an important factor on improving the light extraction efficiency of LEDs.

Abstract

Unwanted cladding light in output of double-cladding fiber lasers has major adverse effect on the beam quality,spectral characteristics,and reliability and stability of lasers.It is of vital importance to strip the cladding light for engineering of the double-cladding fiber lasers.The thermal effect of high power cladding light strippers is studied theoretically and experimentally.The temperature distribution is simulated by means of computational fluid dynamics based on ANSYS.The experiments validate that the temperature simulation is effective and applicable for stripping power ranging from 15 W to 600 W.Furthermore,a kW-level cladding light stripper is optimized based on the thermal simulation.After optimization,the temperature of the stripper declines by up to 46℃,and the stripper can run stably at about 80℃.
