Progress for mode-locked lasers: a tunable pulse duration in finest bandwidth 18 Jun 2025 Shanghai scientists develop ultranarrow bandwidth mode-locked laser with a widely-tunable pulse duration.

Lasers have widespread applications as a light source in a variety of fields, including manufacturing, medicine, high-speed communications, electronics, and scientific research.

This article presents an analysis of the full-bridge voltage inverter widely used to supply dielectric barrier discharges. The main contribution of this article is the deduction of the analytical ...

Li and Bak 1976 (14) showed that isolated excitation of different nerve groups (motor, sensory, pain-conducting fibers) in adult cats may be easier with a short duration pulse. Effects on pulse width ...

Output pulse energy is an important parameter for pulsed lasers. Currently, the literature lacks a general study of the limit of output pulse energies that can be extracted from a given fiber master ...

The influence of pulse duration, gap distance and voltage polarity on the breakdown characteristics are shown. Martin's equation and streamer linear propagation (SLP) model for breakdown voltage ...

We are familiar with the missing pulse detector circuit, which detects the occurrence of a missing pulse in a pulse train where the pulses are of equal duration. But this circuit detects the long ...

Using a quad op amp can help compensate for a lack of rail-to-rail performance in an op amp one-shot design.

It’s an unfortunate fact that a resistor can fail under pulse loads. When pulse power is dissipated to the device’s resistive element, it generates heat and increases the resistor’s temperature.
