在KTiOPO4晶体中,利用来自Ti:蓝宝石再生放大器的0.8 μm基脉冲与白色连续脉冲进行无色散参数混合,产生了覆盖700 nm、约2.4 μm的宽带近红外脉冲。波长范围为1.7 ~ 2.9 μm。与理论带宽的比较表明,非共线相位匹配对光谱展宽有一定作用。
A broadband near‐infrared pulse covering 700 nm around 2.4 μm has been generated by a dispersion‐free parametric mixing in a KTiOPO4 crystal between the fundamental pulse (0.8 μm) from a Ti:sapphire regenerative amplifier and the white continuum pulse. It is tunable within the wavelength region of 1.7–2.9 μm. The comparison with a theoretical bandwidth indicates that the noncollinear phase matching plays a part for the spectral broadening.
