我们提出并演示了一种基于磷硅酸盐光纤（掺P光纤）的全光纤同步泵浦拉曼激光器，用于深层组织多光子成像。该激光器工作在耗散孤子状态，产生2.2 ps啁啾脉冲（可压缩到317 fs），能量高达9.2 nJ，0.3 W的平均功率和1240 nm的中心波长。我们还发现了一种新的交叉偏振拉曼激光操作，提供了一个重要的波长接近930 nm的钙成像。
We propose and demonstrate an all-fiber, synchronously pumped Raman laser based on phosphosilicate fiber (P-doped fiber) for deep tissue multiphoton imaging. The laser operates in a dissipative soliton regime and produces 2.2 ps chirped pulses (compressible to 317 fs) with energy up to 9.2 nJ, 0.3 W average power and at 1240 nm center wavelength. We have also found a new cross-polarization Raman lasing operation that offers access to an important wavelength near 930 nm for calcium imaging.
