Sub-30 fs Yb-fiber laser source based on a hybrid cascaded nonlinear compression approach
文献摘要：
Ultrafast lasers with high repetition rate,high energy,and ultrashort pulse duration have enabled numerous applications in science and technology.One efficient route to generate such pulses is postcompression of high-power Yb-doped lasers.Here,we report on the generation of 24.5 fs pulses with an output energy of 1.6μJ and a repetition rate of 500 kHz.The pulses are obtained by using a hybrid cascaded nonlinear compression of the pulses delivered by a Yb-based fiber chirped pulse amplification[CPA]system.In the first stage,the initial 390 fs laser pulses are compressed to 100.7 fs based on spectral broadening in three fused silica plates.In the second stage,the pulses have been shortened to sub-30 fs by means of nonlinear compression in a hollow-core fiber.Overall,we could achieve～16 times temporal shortening with the proposed approach.The results show that our system can effectively generate few-cycle pulses at a relatively high repetition rate and high energy,which can benefit future possible applications.
