Researchers have developed a new ultrafast laser platform that generates ultra-broadband ultraviolet (UV) frequency combs with an unprecedented one million comb lines, providing exceptional spectral ...
Using the Keck Planet Imager and Characterizer (KPIC), astronomers have performed high-resolution spectroscopic observations of a brown dwarf known as HD 206893 B. Results of the observational ...
Researchers have developed a new smaller, lighter design for space-based imaging spectrometers with high spectral resolution. These high-dispersion imaging spectrometers could be used onboard ...
A Purdue innovation that combines computer vision, color science and optical spectroscopy recovers detailed spectral information from photographs taken by conventional cameras.
The James Webb Space Telescope has detected methane gas on the dwarf planet Makemake, indicating that the distant body is a dynamic icy world.
New excitation method of stimulated Raman scattering achieves natural-linewidth-limit spectral lines
To show the advantage of the natural-linewidth-limit spectral resolution, The team also preliminarily constructed a set of high-density Raman probes with Raman mode intervals down to 12 cm-1, and ...
(a) Schematic diagram of the pump burst and the Stokes burst in the time domain. N: number of pulses in burst. ∆τ: inter-pulse temporal separation. φ: pulse-to-pulse offset phase. Ω R: Raman frequency ...
