Macquarie University researchers have demonstrated a technique to dramatically narrow the linewidth of a laser beam by a factor of over ten thousand – a discovery that could revolutionise quantum ...
Using a diamond crystal measuring just a few millimeters across in a carefully designed cavity, they tested a deliberately "noisy" input beam with linewidth exceeding 10 MHz. Their Raman scattering ...
A project at Macquarie University has demonstrated a way to narrow the linewidth of a laser beam by a factor of over ten thousand. Published in APL Photonics, the technique offers a promising route ...
A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2024.240077 , discusses agile cavity ringdown spectroscopy enabled by moderate optical feedback to a quantum cascade laser. Optical ...
Laser speckle arises from the high spatial and temporal coherence of laser light, generating granular interference that can degrade image quality in numerous applications. Research in this field ...
