LBTEK mid-infrared femtosecond optical parametric amplifier can generate high-power, ultrashort-pulse mid-infrared lasers. Its core principle leverages the parametric amplification effect of nonlinear optical crystals to efficiently convert pump light energy into femtosecond lasers in specific mid-infrared bands. With femtosecond-level ultrashort pulse widths and continuously tunable wavelength characteristics, it adapts to numerous application scenarios. The mid-infrared wavelength tuning range of the LBTEK mid-infrared femtosecond laser covers 6-12 μm, providing stable and high-intensity laser output to meet diverse experimental needs within this band. Meanwhile, the mid-infrared ultra-broadband tunable femtosecond optical parametric amplifier is based on stable optical, Mechanical Engineering, and electronic control designs, enabling flexible wavelength-tunable femtosecond laser pulse output with a wavelength tuning range of 4−16 µm and output pulse width <500 fs. If water cooling is required, the water cooling system must be purchased separately.
