Abstract

We compare the performances of low intensity (~18 nJ/pulse) femtosecond 244 nm grating writing with that of CW (20 mW) 244 nm grating writing for fixed fluencies. We find no evidence of any improvement using pulsed light with duration commensurate with phonon-assisted relaxation away from the excited state.

飞秒脉冲244nm与连续244nm光栅在硼共掺锗硅酸盐光纤中写入的单光子吸收机制

我们比较了低强度(~18 nJ/脉冲)飞秒244nm光栅写入与连续波(20 mW) 244nm光栅写入在固定通量下的性能。我们没有发现使用持续时间与声子辅助弛豫远离激发态相当的脉冲光有任何改善的证据。
