In recent years, there has been an increasing demand for superior mid-infrared high-intensity laser systems, toward applications in nonlinear vibrational spectroscopy, attosecond pulse generation through high-order harmonic generation, and subsequent applications in particle physics. In this research, we utilized Fe:ZnSe, which exhibits broad fluorescence in the 4-micron wavelength band, as the laser gain medium, and developed a seven-pass chirped pulse amplifier.
