高亮度近红外宽带放大自发发射（ASE）是由玻璃包层钛蓝宝石晶体光纤产生的，该光纤是使用共拉激光加热基座生长方法开发的。使用 520 nm 激光二极管作为 a 切、芯直径 18 μm 的钛蓝宝石晶体光纤 (CF) 上的激发源，产生高达 29.2 mW 的 ASE 功率。 3 dB带宽为163.8 nm，辐射亮度为53.94 W·mm(-2) sr(-1)。使用缩减法测量的玻璃包层蓝宝石CF的传播损耗在780nm处为0.017cm(-1)。对于单模应用，超过 100 μW 的功率被耦合到 SM600 单模光纤中。
High-brightness near-infrared broadband amplified spontaneous emission (ASE) was generated by glass-clad Ti:sapphire crystal fibers, which were developed using the co-drawing laser-heated pedestal growth method. As much as 29.2 mW of ASE power was generated using 520 nm laser diodes as the excitation source on an a-cut, 18 μm core-diameter Ti:sapphire crystal fiber (CF). The 3 dB bandwidth was 163.8 nm, and the radiance was 53.94 W·mm(-2) sr(-1). The propagation loss of the glass-clad sapphire CF measured using the cutback method was 0.017 cm(-1) at 780 nm. For single-mode applications, more than 100 μW of power was coupled into a SM600 single-mode fiber.
