飞秒激光离焦抽运熔融石英产生超连续白光的实验研究
Off-focus generation of strong super-continuum emission in fused silica using high power femtosecond laser pulses
摘要
Abstract
We report on the generation of millijoules supercontinuum, which covers waveband from - 400 nm to - 900 nm wavelength, by intense femtosecond laser pulse propagating in 3 mm thick fused silica. The fused silica is placed in front of the geometric focus of incident laser pulse to prevent the breakdown. The dependences of supercontinuurn spectrum on incident pulse energy and off-focus distance of medium are investigated in detail. Our work demonstrates that strong supercontinuum can be generated using off-focus pump of solid transparent medium with energetic incident pulses.关键词
