The results reveal that the amplifier can realize the steady propagation of 38 orbital angular momentum (OAM) modes, and the amplifier exhibits excellent amplification performance, characterized by high mode gain and low threshold power. The threshold power of all modes does not exceed 250 mW, which is conducive to signal amplification. As the pump light has an incident power of 300 mW, a wavelength of 1450 nm, and a wavelength of the OAM signal of 1550 nm, the maximum mode gain of 160.87 dB can be obtained. Compared with the existing orbital angular momentum amplifier, the signal gain has been greatly improved. The proposed amplifier has the advantages of high gain, low threshold power, and a large number of amplified modes, which has significant applications in achieving long-distance stable propagation of OAM and enhancing the capacity of optical fiber communication systems.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"97 5","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147820035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike traditional contact-driven devices, this harvester utilizes a non-contact magnetic coupling structure to achieve efficient energy conversion.

The results show that the number of rotating magnets affects the peak power, rotational speed, and range; at low speeds, it is better to arrange the magnets in the same polarity, and at high speeds, opposite polarities are more favorable; the output power increases with the decrease in the spacing between the rotating and fixed magnets, and the influence of the rotational radius on it is less than that of the spacing, and mode 2 is negatively affected; the number of fixed magnets (when the space is fixed) and the load resistance (there is an optimal value) also have an effect.

The key challenge in achieving high-precision micro-grasping operations lies in suppressing the parasitic displacement of the gripping jaws. This paper proposes a two-stage amplification mechanism with low parasitic displacement to achieve high-precision micro-grasping operations of the microgripper. When the clamping displacement direction of the microgripper aligns with the desired motion direction, parasitic displacement is minimized. The second-stage amplification mechanism is directly connected to the microgripper's output end, which determines the magnitude of parasitic displacement. Among these, a symmetrical compound parallelogram mechanism with flexure hinges is introduced as the second stage to fundamentally minimize parasitic displacement. Simulation results show that the proposed externally actuated microgripper with displacement compensation achieves a parasitic displacement rate of only 0.158%. Experimental results demonstrate that under an air pressure of 0.6 MPa, the prototype achieves a total output displacement of 490.3 μm, a total amplification ratio of 29.1, and a measured first-order natural frequency of 1625 Hz. The experimental results validate the rationality of the design, indicating the potential of this microgripper for micromanipulation tasks requiring both a large stroke and high precision.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"97 5","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147820026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering the characteristics of a rotary magnetorheological damper (MRD) that has controllable torque and fast response, a servo motor and a rotary MRD are combined to form a VSA. The principle of variable stiffness drive is analyzed according to the frame of the VSA. The rotary MRD for the VSA is designed, and the electromagnetic field distribution in the damper is analyzed with the finite element method. Then, the torque and magnetomotive force value of the damper are calculated. Based on the configuration of the VSA and the mechanical characteristics of the damper, the variable stiffness control method is proposed. Based on these factors, the rotary MRD and the VSA are developed, and the performance tests are worked out. The experimental results show that the test results of the damper torque are close to the calculation results, and different stiffness coefficients can be set in the control program of the VSA. The test results of the stiffness coefficients are close to the set values. Moreover, the approach proposed in this article provides valuable insights into the utilization of rotary MRD for the development of variable stiffness robotic systems.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"97 5","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147841898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A two-stage 4He circulation (∼20 and ∼2 K) precools a continuous-flow STM insert, after which another circulation loop, filled with either 3He or 4He, is liquefied and further cooled by evaporative pumping. The sample stage reaches base temperatures of 420 mK (4He-3He mode) and 894 mK (4He-4He mode). The temperature fluctuations of approximately ±0.1 mK are achieved at 500 mK and 1 K under proportional-integral-derivative control. Characterization, including cooling curves, current noise, thermal drift, atomic-resolution imaging, and variable-temperature/magnetic-field spectroscopy, demonstrates the performance comparable to conventional liquid-4He bath-based STM systems in terms of resolution, stability, and tunability. Furthermore, the system enables a months-long continuous operation across a wide temperature range, featuring straightforward magnet upgradability, direct high-temperature baking capability, and compactness with low installation requirements.

In this paper, a compact spectrometer operating in the 24-32 nm band is presented, enabled by a near-normal-incidence spherical mirror coated with an aperiodic Al(1.5%Si)/Zr multilayer specifically designed to exhibit a monotonic, gradient-reflectivity profile. The multilayer was optimized using interactive multilayer design to provide a broadband response with a reflectance increasing from ∼5% to ∼20% toward the long-wavelength end, thereby compensating for the intrinsic efficiency roll-off of the other optical elements in this band. Synchrotron measurements confirm that the fabricated coating closely reproduces the designed peak position, bandwidth, and gradient behavior of reflectivity. With this system, single-shot laser-produced plasma EUV emission from high-purity W, Mo, Fe, Cu, Cr, Si, and Al targets was systematically characterized, revealing the optimal excitation power density and multi-shot lifetime behavior for each material within this spectral range. Overall, this spectrometer achieves a spatial resolution of ∼31 μm and maintains a spectral resolution better than 0.2 nm across the full 24-32 nm band, establishing a compact and high-performance solution for broadband EUV source diagnostics.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"97 5","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147841930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
