We presented an ultrashort pulse generation in an erbium-doped fiber laser cavity using MAX-PVA as a mode-locker. A thin film of SA was prepared by mixing PVA with Ti₃AlC₂ as a saturable absorber inside the laser cavity. The optical nonlinearity was also demonstrated, revealing a saturable absorption of 2%, a non-saturable absorption of 58.2%, and a saturation intensity of 1.63 MW/cm². The excellencies of MAX-PVA was proven as it initiates ultrafast laser with a duration of 3.68 ps corresponds to a repetition rate of 1.887 MHz. The ease of preparation, together with its superior optical, physical, thermal, and mechanical properties, makes it a favorable SA for pulse generation in an all-fiberized laser cavity.

我们介绍了使用MAX-PVA作为锁模器在掺光纤激光器腔中产生超短脉冲的方法。通过在激光腔内将PVA与作为可饱和吸收剂的Ti ₃ AlC ₂混合来制备SA薄膜。还证实了光学非线性，显示出2％的饱和吸收，58.2％的非饱和吸收和1.63MW / cm ²的饱和强度。事实证明，MAX-PVA的卓越之处在于它以3.68 ps的持续时间启动了超快激光，对应于1.887 MHz的重复频率。易于制备，再加上优异的光学，物理，热和机械性能，使其成为在全纤维化激光腔中产生脉冲的理想SA。
