We present a low-intensity noise single-frequency Yb-doped all-fiber amplifier oriented to
space-borne gravitational wave detection. Relative intensity noise (RIN) below −70 dBc/Hz @ …

We demonstrate an extended Kalman filtering-enhanced linewidth measurement in short-delay
self-heterodyne interferometry (SDSHI). We found that a modified SDSHI trace closely …

Effective evaluation of multi-hop tool use is critical for analyzing the understanding, reasoning,
and function-calling capabilities of large language models (LLMs). However, progress …

Featured Application An online measurement method with a measurement cell to estimate
internal parameters (small-signal gain coefficient, internal optical losses, the saturation …

The non-cooperative dual-base radar provides superior performance in terms of safety and
robustness of target detection. This paper presents a series of experimental maritime target …

Because of the effect of carrier frequency hopping, the input IF signal of carrier tracking loop
in DS/FHSS (Direct Sequence/Frequency Hopping Spread Spectrum) TT&C (Telemetry, …

Background Although laparoscopic splenectomy (LS) has become the standard approach
for most splenectomy cases, some areas still remain controversial. To date, the indications …

We report on an injection seeded 1 kHz single frequency pulsed Nd: YAG ring laser with
pulse energy of 5.2 mJ and pulse width of 9.9 ns. The ramp-fire technique is used to maintain …

We demonstrate a 202 W all polarization-maintaining (PM) single-frequency fiber amplifier
operating at C band. Simulations show that the length of the output fiber pigtail following the …

After analyzing the circuit features, generalizing the typical faults, and combining the
experience of maintenance, a design of fault diagnosis instrument based on the fault dictionary …
