The core diameter mismatch between the SMF and GIMF induces MMI and enables efficient coupling of high-intensity light, effectively replicating the behavior of a saturable absorber (SA). Fundamental soliton pulses with a repetition rate of 20.89 MHz and a maximum pulse energy of 0.23 nJ were obtained within a pump range of 23.18 to 66.23 mW. As the pump power increased above 66.23 up to 103.12 mW, the laser transitioned to second-order harmonic mode-locking, doubling the repetition rate to 41.70 MHz. This transition arises from gain depletion and pulse peak clamping within the cavity, leading to pulse splitting and harmonic generation. The HML pulses operated at 1573.8 nm with a duration of 290 fs and an exceptionally high signal-to-noise ratio (SNR) of 80 dB, confirming excellent stability.

However, traditional detection methods have limitations such as complex sample processing and weak anti-interference ability. In this regard, this study proposes a chiral molecular enantiomeric selectivity sensor based on double-hole optical fiber (DOF). Multi-parameter detection is achieved by integrating surface plasmon resonance (SPR) and Mach-Zehnder interferometer (MZI) technologies. It innovatively adopts a cascade structure of single-mode fiber (SMF)- multimode fiber (MMF)-DOF.

This design can achieve specific recognition of liquid (R)-(+)-anatabine and (S)-(−)-anatabine. Moreover, single-mode optical fibers and dual-hole optical fibers can be combined to form MZI, which serves as the sensing channel 3 to eliminate temperature interference.
