Titanium trisulfide (TiS3) is regarded as a candidate material for optoelectronic devices and nano-transistors due to its photoresponse. However, its nonlinear optical response in a mode-locked laser is yet to be investigated. Here, the performance of TiS3 as a saturable absorber in a mode-locked laser is demonstrated. The generated mode-locked pulses achieve pulse duration as short as 147.72 fs at 1555 nm, which indicates that TiS3 as a potential functional material has applications in nanomaterial-related photonics.Titanium trisulfide (TiS3) is regarded as a candidate material for optoelectronic devices and nano-transistors due to its photoresponse.

三硫化钛的饱和吸收特性及飞秒锁模应用

三硫化钛 (TiS3) 因其光响应而被视为光电器件和纳米晶体管的候选材料。然而，它在锁模激光器中的非线性光学响应还有待研究。这里展示了 TiS3 作为锁模激光器中可饱和吸收体的性能。产生的锁模脉冲在 1555 nm 处实现了短至 147.72 fs 的脉冲持续时间，这表明 TiS3 作为潜在的功能材料在纳米材料相关的光子学中有应用。 三硫化钛 (TiS3) 被认为是光电器件的候选材料和纳米晶体管由于其光响应。然而，它在锁模激光器中的非线性光学响应还有待研究。这里展示了 TiS3 作为锁模激光器中可饱和吸收体的性能。
