Ultrafast science-the study of highly complex and extremely short-lived transient events-has become an area of significant interest in the materials sciences, physics, chemistry, and biology. This article focuses on the state-of-the-art instrumentation and a few of the available probes and techniques, and intends to give a brief overview of the possibilities and challenges for ultrafast materials sciences and for the instrumentation that is required. The pulsed laser-material interactions are briefly introduced, since they are the principal methods to access and trigger ultrafast processes in materials. The associated time and length scales and a few experimental possibilities in the materials sciences are discussed in the first part of this article. The second part deals with the two most applicable types of pulsed probes, x-rays and electrons, and the associated methods to interrogate ultrafast processes. Emphasis is on their differences, capabilities, and limitations.
