Abstract: Femtosecond, broadband stimulated Raman spectroscopy is a popular approach to measuring molecular dynamics with excellent signal-to-noise and spectral resolution. We present a new method for broadband stimulated Raman spectroscopy that employs Kerr instability amplification to amplify the supercontinuum spectrum from sapphire and create a highly tunable Raman probe spectrum spanning from 530 to 1000  nm (–6000 to 2800 cm–1). Our method, called Kerr instability amplification for broadband-stimulated Raman spectroscopy (KAB-SRS) provides an alternative to optical parametric amplifiers by producing a broader and more tunable spectrum at a significantly reduced cost to OPA implementations. We demonstrate the effectiveness of KAB-SRS by measuring the stimulated Raman loss spectrum of 1-decanol.

Bioinspired directional structures for inhibiting wetting on super-melt-philic surfaces above 1200 °C

Bioinspired directional structures created by #femtosecond #LaserAblation resist wetting from high‑temperature molten CMAS droplets, enhancing contact angles and reducing spreading, providing a facile strategy for super‑melt‑philic surface protection.

Shining a light on dark valleytronics Using one of the most advanced spectroscopy setups worldwide, researchers have created a recipe for research into next-gen quantum information technologies.

Dark Valleytronics [via OIST] 🧪🥼🔬⚛️⚫ℹ️

"in #valleytronics, the crystal structure of unique materials enables us to encode information into distinct momentum states of the electrons, known as valleys."

Don't be silly 10W powered fs laser is always < 10 W laser

It's easily to claim any impulse laser to have peak power 1000 times higher.

So any 10W impulse laser can be claimed to have peak power of 10 kW

Peak power of fs laser is fake marketing term

@lightconversion.bsky.social steps into its 31st year with a pocketful of milestones collected during its 30th jubilee.

Here’s to another 30 years of driving world-class change with best-in-class #femtosecond #laser systems!

@lightconversion.bsky.social completed the installation of its ORPHEUS-OPCPA at @icfo.eu, the Attoscience and Ultrafast Optics group, led by Prof. Dr. Jens Biegert.

Pumped by the #PHAROS #femtosecond #laser, the system will be used for soft X-ray generation and spectroscopy in the water window.

Discover how @lightconversion.bsky.social’s industrial-grade #femtosecond #lasers can give you a competitive advantage in your high-precision applications at #MDMWest. Meet the company experts at booth #2026 on February 4–6.

Seems like there is a new ultracompact #femtosecond #laser source for #multiphoton #microscopy in town! 50 MHz rep rate means a 2-3 m cavity if there is a single pulse circulating in the cavity - folding that into that compact of a form factor is quite impressive!

Attosecond analysis illuminates a watery mystery With powerful x-ray free-electron lasers, researchers are making great strides in ultrafast spectroscopy—with lessons about how molecules arrange themselve

In a new experiment a sample was excited with an x-ray pulse and then probed with another, all in under a #femtosecond. When they tried using it with liquid #water, their results had more to say about water’s equilibrium structure than about its subfemtosecond dynamics.
