Ultrahigh-speed laser drilling of transparent materials via transient electronic excitation.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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
Femtosecond lasers with extremely high peak intensity have driven remarkable advancements in manufacturing across science, medicine, and industry. However, the problem of notably low machining speed remains unsolved. Here, we demonstrate that by transiently exciting electrons in a transparent material, the laser drilling speed is increased by a factor of 1 million compared to that in multishot percussion drilling. By irradiating with a single shot of a spatially shaped ultrashort laser pulse, the optical properties are momentarily changed on the picosecond scale, making the material considerably easier to machine by a successive laser pulse. The selective absorption of laser energy in regions with excited electrons leads to the rapid heating and evaporation of material at an extraordinarily high speed. Furthermore, the machining is achieved using a low-power light source, four orders of magnitude lower than conventional femtosecond lasers. The concept of transiently altering material properties is expected to usher in a paradigm shift in research and development for manufacturing.
