We demonstrate an all-fiber, compact-structure, high-sensing-efficiency temperature sensor using a resonator structure sensor device of a runway type and MXene V2C. The high-quality functional material MXene V2C, synthesized by a simple two-step method, has excellent photothermal conversion performance. As-prepared MXene V2C is integrated into the runway section of a runway-type microfiber knot resonator based on the coupling mechanism between the surface near the field of the fiber and materials. When the temperature variation range is ~25–70 °C, the corresponding transmission light intensity variation is linear, and the maximum normalized sensing efficiency is 2.21 dB/°C/mm. Our work demonstrates that the runway-type structure ensures the compactness of the sensor device and enhances the interaction distance between the material and the microfiber, which provides additional integration strategies for functional material-based sensor devices.

“…GDY is a narrow band gap semiconductor with a lower electron-hole recombination rate and a faster optical response speed, thus possessing stronger nonlinear optical properties. Based on the strong third-order nonlinear effect of GDY, the shortest output pulse width in an erbium-doped GDY saturable absorber fiber laser is 135.8 fs to date [24]. In the field of solid-state lasers, GDY saturable absorber is used in PQS Yb:SSO lasers to achieve a pulse output with a repetition rate of 43.6 kHz, a pulse width of 4.153 µs, and an average output power of 0.393 W. Improving the modulation parameters of the saturable absorber is necessary to realize a higher-performance pulsed laser.…”

All-solid-state Tm lasers have a wider wavelength range and higher output power compared to other types of lasers. In this work, we demonstrate an all-solid-state, high repetition, Tm:YAP laser Q-switched by a graphdiyne (GDY) saturable absorber. The high-quality optical nonlinear material GDY, synthesized by a cross-coupling method, exhibits a strong nonlinear optical response. The application of GDY as a saturable absorber in the passively Q-switched (PQS) Tm:YAP of an all-solid-state laser has been realized with the shortest pulse duration of ~785 ns and repetition frequency of ~199.6 kHz at a central wavelength of 1985.8 nm. This represents the shortest pulse duration and the highest repetition frequency achieved from GDY in a solid-state Tm laser to date. Our work demonstrates the remarkable nonlinear optical properties of GDY, which holds promising potential in the field of optoelectronics.

“…A femtosecond pulsed laser with a pulse width of about ten femtoseconds can contain millions of spectral components, which is equivalent to millions of continuous wave lasers with different center wavelengths but the same repetition frequency. Femtosecond pulsed laser has been widely used in optical fiber, [16][17][18] micromachining, [19][20][21] and nonlinear optics. [22][23][24] The demand for ultrafast and real-time imaging is increasing with the deepening of scientific research.…”

Pulsed digital holography, which combines femtosecond pulsed laser and digital holography, is a novel technology for detecting ultrafast transient processes in real-time. Pulsed digital holography can obtain a series of amplitude and phase information of the ultrafast process in one shot at the femtosecond or picosecond order, and comprehensively characterize the whole picture of the ultrafast process. However, the system of pulsed digital holography currently has the defects of complexing, poor stability, small number of pulse frames, and low utilization of space bandwidth, which seriously limits practical applications. In this work, a real-time detection system is designed for ultrafast transient processes, which has the property of high stability, femtosecond or picosecond time order resolution, and adjustable pulse frames. The pulsed lasers are used instead of traditional continuous lasers. The proposed system design provides a competitive approach to ultrafast transient imaging.
