Abstract ：
We demonstrate a high-energy 780 nm wavelength band femtosecond laser by utilizing single-pass frequency doubling all-PM Er-doped fiber amplifier (EDFA) in a periodically-poled lithium niobate (PPLN) crystal. The high power 1560 nm laser is realized based on chirped pulse amplification (CPA) technology, which has obtained the average power of 3.02 W, repetition frequency of 1.03 MHz, and pulse width of 640 fs. Subsequently, by using a PPLN crystal as frequency doubling element, a maximum output power of 0.46 W with 620 fs pulse width at 780.29 nm is generated, the corresponding pulse energy is 0.44 mu J and the peak power is 0.71 MW. To the best of our knowledge, the 0.44 mu J laser output in 780 nm wavelength band is the highest pulse energy generated from a frequency doubling femtosecond Er-doped PM fiber laser.

Abstract ：
We report a 4.3 pm mid -infrared (mid-IR) high -power amplified spontaneous emission (ASE) fiber source based on CO 2 -filled nested hollow -core anti -resonant fiber (Nested HC-ARF). The pump source is a homemade hundred -watt -level wavelength -tunable 2 pm single -frequency fiber laser. A 5.7 m long 8 -tube Nested HC-ARF is used as the gas cell, with a core diameter of 110 pm and cladding diameter of 400 pm, which exhibits transmission loss of 0.1 dB/m at 2 pm and 0.24 dB/m at 4.3 pm respectively. To improve the coupling efficiency of the high -power pump laser and reduce the influence of the thermal effect at the input end of the hollow -core fiber, the fiber is designed for multimode transmission at the pump wavelength. A continuous wave output power of 6.6 W at 4.3 pm is achieved, and the slope efficiency is 17.05%. To the best of our knowledge, it is the highest output power for such gas -filled HC-ARF ASE sources in 4 - 5 pm. This work demonstrates the great potential of gas -filled HC-ARF generating high -power mid-IR emission.

Abstract ：
In this work, a novel Nd3+-doped silica fiber preform was fabricated by the UV-curable nanocomposite technology combined with the solution doping method. The preform sample had a great homogeneity with a doping concentration of 1.14 wt% Nd3+ ions and 2.51 wt% Al3+ ions. The obtained Nd3+-doped core glass provided a relatively large emission cross section (-0.84 pm2) and a long lifetime (373 mu s) of 916 emission. On this basis, by using an 808 nm laser diode as the pump source, lasing at 916 nm was achieved from a 4 cm long fabricated Nd3+-doped silica fiber, with the corresponding slope efficiency of -13.6 %. Notably, only 2 cm-short created fiber alone was enabled for 916 nm lasing generation. Our results indicated that the created Nd3+ doped fiber by the novel approach has unique advantages and potential for compact short-cavity 0.9 mu m laser applications.

Abstract ：
Flexible and wearable textile -based triboelectric nanogenerators (TENGs) have attracted extensive attention in wearable electronics owing to their ability to convert waste mechanical energy from human motion into electrical energy. However, the performances of TENGs are lower than those of planar/film configurations due to the complex fiber fabrications and limited mechanical freedom. In this work, we demonstrate an extrusion method combined with thermal drawing (ETD method) for continuous and scalable triboelectric fiber fabrication, providing longitudinal uniform fibers for hundreds of kilometers. Based on the ETD method, super -elastic microstructured triboelectric fibers (SMTFs) were fabricated, consisting of hollow elastomeric and liquid metal cores (EGaIn). The SMTFs showed excellent superelasticity with clear and uniform microstructures. The fibers could withstand strain up to 1800% and exhibited excellent electrical output performance. Utilizing a single fiber as the medium for triboelectric energy collection, the average open circuit voltage and instantaneous power density are respectively up to 210 V/m and 21 mu W/m with a 40 M omega external load resistance. The SMTFs could also be woven into deformable textiles with high electrical outputs up to 160 V, 10 mu A, and 50 nC. In addition, the SMTFs-based textiles were further demonstrated as completely soft and stretchable components for self -powered sensing in smart home applications.

Abstract ：
In this work, we present an all-fiber structured parametric oscillator capable of directly generating pulses within the 900 nm wavelength range. Leveraging the four-wave mixing effect within photonic crystal fibers, the oscillator converts the 1030 nm pump light into two distinct sidebands centered at 900 nm and 1250 nm. Employing time-dispersion-tuning techniques, we achieved a remarkable continuously tunable wavelength range spanning 60 nm, from 865 nm to 925 nm. These pulses exhibited a pulse width of 3.2 ps and a peak power of 500 W at 900 nm, with a repetition rate of 30.6 MHz.

Abstract ：
We report a 3.1 mu m high-power amplified spontaneous emission (ASE) source in nanosecond pulse regime based on a 10-m-long acetylene-filled nested hollow core anti-resonant fiber (HC-ARF). By pumping with a homemade 1.5 mu m high-power repetition-rate-tunable nanosecond pulse single-frequency fiber laser, a maximum output power of 15 W ASE pulse light has been achieved with a repetition rate of 5 MHz, a pulse width of 58 ns, a pulse energy of 3 mu J, and a peak power of 51.7 W. To the best of our knowledge, it is the highest output power for such gas-filled HC-ARF nanosecond pulse ASE sources in 3 similar to 4 mu m mid-infrared (Mid-IR) region. In addition, we characterize the pulse width evolution at the pump laser's repetition rate of 1 MHz, 3 MHz, and 5 MHz. When the 1.5 mu m pump laser operates at a repetition rate of 1 MHz and a pulse width of 70 ns, the 3.1 mu m ASE's narrowest pulse width of 11 ns is realized, which is owing to the gain saturation effect occurs during the Mid-IR pulse amplification. This research demonstrates the capability of hollow core fiber gas lasers for high-power Mid-IR pulse generation and provides new opportunities for efficient pulse narrowing.

Abstract ：
Hollow-core anti-resonant fibers (HC-ARFs) are widely used for high-power laser transmission owing to their low nonlinearity and high damage threshold. However, most existing structural designs are suitable for single-mode guidance but are inadequate for efficient transmission of few- or multi-mode lasers with high output power. In this study, we fabricated a low-loss multi-mode 8-tube nested hollow-core anti-resonant fiber (Nested HC-ARF) with a minimum loss of 3.27 dB/km at 1 mu m wavelength, which enabled the efficient transmission of at least five mode groups. Accordingly, we demonstrated the transmission of a record 3 kW few-mode (M-2 similar to 1.38) continuous-wave laser with a maximum transmission efficiency of 95.2% using a 10 m multi-mode Nested HC-ARF and an optimized transmission system. The experimental verification of the beam quality and spectrum indicated distortion-free transmission, which paves the way to power delivery on the scale of tens of kilowatts.
