我们描述了一种 Er3+ 掺杂铝硅酸盐芯光子晶体光纤激光器，该激光器结合了分布式布拉格反射器，该反射器由通过光学相位掩模的双光子 193nm 照射写入作为反馈元件。该激光器采用 980nm 波长的二极管泵浦，并且观察到双线宽激光器运行接近阈值的证据。然而，在较高的泵浦水平下，竞争者会优先选择一条激光线。
We describe an Er3+-doped aluminosilicate core photonic crystal fibre laser incorporating distributed Bragg reflectors written by two-photon 193nm irradiation through an optical phase mask as the feedback elements. The laser is diode pumped at 980nm and evidence of dual linewidth laser operation close to threshold is observed. However, at higher pumping levels gain competition preferentially selects one laser line.
