Single-shot ultrafast optical imaging can capture two-dimensional transient scenes in the
optical spectral range at≥ 100 million frames per second. This rapidly evolving field …

Femtosecond laser technology has attracted significant attention from the viewpoints of
fundamental and application; especially femtosecond laser processing materials present the …

The extreme electro-optical contrast between crystalline and amorphous states in phase-
change materials is routinely exploited in optical data storage and future applications …

We propose and experimentally demonstrate a new method called SF-STAMP for
sequentially timed all-optical map** photography (STAMP) that utilizes spectral filtering …

Photonic topological insulators (PTIs) have been proposed as an analogy to topological
insulators in electronic systems. In particular, two-dimensional PTIs have gained attention for …

In this work, the local structure of metastable Ge 2 Sb 2 Te 5 (GST) phase change thin films
crystallised by laser irradiation of amorphous GST films is studied by state-of-the-art …

We captured ultrafast two-dimensional (2D)-burst images of the crystalline-to-amorphous
phase transition of Ge 2 Sb 2 Te 5. These transitions were induced by a femtosecond laser …

Halide perovskites are a class of semiconductors with strong direct interband transition and
high mobility of charge carriers resulting in bright luminescence, which can be easily tuned …

This article presents the results of irradiation treatment by the 180 fs laser pulses at the
wavelength of 1030 nm of Ge2Sb2Te5 amorphous thin films. It is shown that high‐quality …

A promising route for manufacturing emergent metamaterials is the use of ultrafast laser
pulses in complex alloy processing. Laser-induced structural transformations in Zr-based …
