Summary: A novel erbium-doped random fiber laser optical switch with rapid response and simple structure is proposed in this study. By using a liquid crystal-filled photonic crystal fiber as the sensing unit, a high-extinction ratio laser switch is achieved. The optical switch has the advantages of low cost, high sensitivity, and strong anti-interference ability.

Summary: We developed an erbium-doped fiber-based saturable absorber (SA) using niobium aluminium carbide (Nb2AlC) nanomaterial, which can generate stable mode-locked pulses. The SA was fabricated with polyvinyl alcohol (PVA) and the Nb2AlC nanomaterial, producing pulses operating at 1530 nm with a repetition rate of 1 MHz and pulse width of 6.375 ps. A peak pulse energy of 7.43 nJ was achieved at 175.87 mW pump power. This study not only provides design suggestions for SAs based on MAX phase materials but also demonstrates the great potential of MAX phase materials for generating ultra-short laser pulses.

Summary: In this experiment, a single-frequency distributed Bragg reflector fiber laser at 915 nm was achieved using a 2.5-cm Nd3+-doped phosphate fiber, resulting in an output power of 13.5 mW at an absorbed pump power of 240 mW. The experimental results indicate that Nd3+-doped phosphate glass fiber is more efficient than Nd3+-doped silica glass fiber for single-frequency laser operation in the 900 nm wavelength range.

Summary: This paper investigates the use of nanodiamond particles as a saturable absorber in Erbium-doped fiber lasers to generate stable Q-switched pulses, demonstrating the promising potential of 10% nanodiamond as a material for various photonic applications. The results showed that the fabricated nanodiamond saturable absorber could produce stable laser pulses, with the Q-switched fiber laser achieving a self-start of stable Q-switch pulses at a specific pump power. The study highlights the stable performance and potential applications of nanodiamond-based saturable absorbers in fiber laser technology.

Summary: A novel multi-wavelength erbium-doped fiber laser with wavelength switchable capabilities is demonstrated based on PDL modulation and cascaded FBGs as wavelength comb filters. The PDL modulation balances the total loss and lasing gain, allowing for the creation of multiple lasing lines by adjusting PDLs in different wavelengths. The experiment successfully verifies the switching operation for single to four-wavelength laser outputs by adjusting the polarization controllers.

Summary: This study proposed a novel approach to improve the performance of an erbium-doped fiber laser by combining two narrow-band optical filters in the laser cavity, optimizing the cavity configuration, and inserting an unpumped erbium-doped fiber. Experimental results showed that the fiber laser exhibited excellent power stability and linewidth, while also achieving Q-switching control.

Summary: A widely wavelength tunable mode locked Er-doped fiber laser oscillator based on NPR effect achieved continuous wavelength tunable mode locked operation and set a new record. The high SNR of the output pulses was superior to typical values reported in most papers. Additionally, by adjusting the width of the slit, the pulse duration and spectral bandwidth could be tuned accordingly.
