| Outline of Final Research Achievements |
In this study, a broadband, high power mid-infrared (MIR) light source pumped by an Yb fiber laser system for a real time MIR spectroscopy have been investigated. At first, the Yb fiber chirped pulse amplification system having 615mW with pulse duration of 200 fs at 40 MHz repetition rate was developed. Then, the output power of 3W level was obtained by using a double-clad Yb fiber amplifier. Furthermore, an optical parametric amplifier system was constructed to obtain the MID IR pulse. Finally, a time-stretch dispersive Fourier transformation (TS-DFT) as an ultrafast spectrum measurement technique have been successfully demonstrated. This study open for new opportunity in the ultrafast MIR spectroscopy.
