1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Output power of a laser device critically defines the application prospects. Colloidal quantum dots (QDs) have emerged as auspicious laser media; however, the exclusively low-power emission obscures the practical deployment. Here, we resolve this challenge by designing an architecture of QD laser with unprecedented peak powers in megawatt regime. The achievement is enabled by integrating the QDs with exceptional gain metrics with a seed-amplifier laser structure. Transient spectroscopy and theoretical simulation reveal that the narrow emission linewidth and large biexciton binding energy of the QDs act synergistically to enable an enhanced gain performance with submonoexcitonic threshold and record high-saturated gain cross section. A Littman-Metcalf cavity is designed to deliver the continuously tunable laser emission, and the synchronous amplification reaches the megawatt output. The high-power QD laser exhibits high spatial coherence, linear polarization, and operational endurance, which has proved effective as the pump source for spectroscopic research.
