The investigation of a fiber laser utilizing ytterbium-doped hybrid passively mode-locking, featuring a novel copper oxide-doped zinc oxide saturable absorber (CuO-ZnO SA), has been realized. The hybrid mode-locked (hybrid-ML) fiber laser integrates the nonlinear polarization rotation (NPR) technology with the CuO-ZnO-SA, producing remarkable characteristics with a central wavelength of 1045 nm, a 3-dB bandwidth spanning 18.26 nm, an ultra-short pulse width of 98 fs, a repetition frequency of 1.96 MHz, and an impressive signal-to-noise ratio of 51 dB. This research demonstrates a substantial enhancement in laser performance compared to NPR mode-locking alone. Notably, the pulse width experiences a significant compression, reduced by 39 fs, while the signal-to-noise ratio sees a noteworthy improvement of 11 dB. Furthermore, when contrasted with passively mode-locked pulse lasers relying solely on NPR technology, the hybrid passively mode-locked fiber laser attains a substantial reduction in output pulse width, surpassing 98 fs. These findings show the significant potential of the hybrid-ML system in the realm of ultrafast lasers, offering a promising avenue for future applications in cutting-edge research and technology.
