Radiation Resistance of Optical Fiber Via High Optical Power Injection:An Experimental Study
摘要
Abstract
To enhance the radiation resistance of the optical fiber pressure measurement system,the interferometric configuration is upgraded and the factors limiting the launch power are analyzed,and the specific parameters of the laser are discussed.A test optical path with adjustable optical power is designed.Transient radiation experiment is carried out by using γ pulse radiation source with radiation dose rate of 1×109 Gy·s-1,a pulse width of about 100 ns,and the average photon energy of 1 MeV.At the same time,the instantaneous radiation-induced loss of single-mode quartz fiber is obtained when the injected light wavelength is 1 550 nm and the optical power is 31.25,125,500,2 000 mW in turn.The experimental results show that the peak value of radiation loss of the test optical fiber with higher injected power is lower,and the performance recovery speed of the fiber is faster,and the radiation resistance of the fiber measurement system is stronger.The difference of radiation-induced loss and recovery speed of optical fiber under different optical power is obtained,and the mechanism of high power fiber reinforcement is analyzed,which provides useful reference for fiber radiation reinforcement.关键词
