The article reports that the race to help save the planet by producing clean energy is on and high-intensity lasers using chirped-pulse amplification are being explored for fusion energy. Why? It's a promising avenue for clean energy production because it's safe, environmentally friendly, and efficient. A startup fusion company, Focused Energy (Austin, TX), is working on an ambitious project to field a credible ignition experiment by the end of 2029.

The article focuses on the Ultrafast lasers which enable new biological capabilities. Topics discussed include the particular features of femtosecond laser interaction also enable new methods of directly interacting with biological material, modifying function cell by cell; and unique interaction introduces distinctive capabilities in microfabrication and direct manipulation of living cells.

The article reports that University of Michigan's Gérard Mourou Center for Ultrafast Optical Science is home to the Zettawatt Equivalent Ultrashort-pulse laser System (ZEUS) appealing to researchers exploring extreme plasmas. Topics include ZEUS's petawatt laser pulse collides with a gigaelectronvolt (GeV) energy electron beam generated by the beamlines; and geometry provides the equivalent of a zettawatt power laser interaction within the rest frame of the electron beam.

The article discusses the concept of tapered double-clad fiber amplifiers and its functions and importance in the field of industrial processing. Topics discussed include the important role of ultrafast lasers with pulse duration in industrial processes including the processing of athermal materials, application of cladding-pumped fiber architectures, and the barriers to the widespread adoption of ultrafast high-powered laser technology.

The article offers information about the ultrafast lasers adopted in next-generation positioning, navigation, and timing (PNT) systems used in space. It explores the opportunity to use a modern bonding bench to reduce the entire femtosecond laser to a palmsized format. It demonstrate a full optical frequency comb configuration suitable for atomically referenced timing and navigation applications.

The article discusses that the optical frequency combs emit a spectrum of frequencies that are perfectly spaced like the teeth on a comb, and two such frequency combs with slightly different pulse-repetition rates are sometimes combined to create a dual-comb setup emitting a stream of short pulses.

The article discusses coherent wake emission(CWE) and attosecond pulses. It states that a pan-European team of researchers have successfully created isolated attosecond pulses with unprecedented intensity. This makes use of few-cycle, femtosecond-scale pulses to ablate the surface of a mirror, creating a plasma. CWE is a kind of push-pull effect on the plasma electrons. It mentions that short pulses were created by exploiting CWE.
