(Nanowerk News) Exciton-polariton lasers, renowned for their low-power operation, have long tantalised researchers with their promise for practical low-energy applications. However, until now, a clean ...
A new publication from Opto-Electronic Advances, DOI 10.29026/oea.2023.210149, discusses ultra-high spectral purity laser derived from weak external distributed perturbation. Laser has the ...
Defining laser-beam power density. Power spectral density (PSD) is the measure of a signal's power content versus frequency. PSD gives designers an idea of how the power of a signal is distributed ...
Researchers developed a new type of spectral shaper that can shape the spectrum of 10,000 lines of light from a laser frequency comb. The image shows the spatial light modulator they used with a 2D ...
